Materials for Proton Exchange Membranes and Membrane Electrode Assemblies for PEM Fuel Cells


Materials for Proton Exchange Membranes and Membrane Electrode Assemblies for PEM Fuel Cells

The global market value of components for PEM fuel cell membrane electrode assembly (MEA) as defined by the membrane, the bipolar plates, the gaseous diffusion layers, and the catalyst ink and electrodes, is an estimated $383 million in 2010. This market is expected to grow at a 20.6% compound annual growth rate (CAGR) over the 5-year forecast period to reach $977 million in 2015.
Of the PEMFC MEA components, membranes have the greatest value, estimated at $200 million in 2010. By 2015, this sector will be worth $424 million, a compound annual growth rate (CAGR) of 16.2%.
Inks and catalysts have the second largest share but will experience the highest growth rate of the aforementioned components. This sector is valued at $103 million in 2010 and is forecast to increase at a 28% compound annual growth rate (CAGR) to reach $354 million in 2015.

INTRODUCTION
STUDY GOALS AND OBJECTIVES
This analysis focuses on the three main components of the membrane electrode assembly (MEA) for proton exchange membrane fuel cell (PEMFC). These include:
  • Membranes
  • Gaseous diffusion layers and bipolar plates
  • Catalysts and inks
Polymer membranes that are the electrolyte and therefore the heart of the fuel cell, and they receive extra attention. The report also examines the history and advancing technology of these components, the companies involved in these developments, the current and projected incentives, and the projected markets for such technologies.
Identified as a practical solution to many of the technological and environmental problems facing the world today, the proton exchange membrane (PEM) fuel cell is appropriate as a power source for transportation, stationary distributive power, and small-scale applications such as portable electronic products. Applications for all types of fuel cells are still evolving. In the process of this evolution, the different proton exchange membrane materials and MEAs will evolve and be adapted to more specific uses.
Identifying how researchers are solving the search for better membranes that have greater tolerances to poisoning, greater durability, and lower costs is a major objective of the report. The U.S. Japanese, Chinese, and European Union governments are pouring billions of dollars of loans, subsidies, and outright grants into fuel cell research and development — and at the same time there has been a series of brutal confrontations between Congress and the President’s administration over continued fuel cell vehicle funding. Meanwhile, European and Far Eastern government subsidies increase.
Commercialization of the fuel cell is not solely influenced by engineers and scientists working on stacks and reformers. (This is also brought about by subsidies by the government, lobbying efforts, venture capitalists, and most of all by some consumers actually finding a need or desire for the product.) A major cost issue addressed is the critical issue of the catalyst component.

REASONS FOR DOING THE STUDY
Fuel cells are viewed as potential candidates for auxiliary power, mobile power, stationary distributed or central power, and portable product power. Advances in the technology are made, but sometimes these advances reveal even more challenges to be met. Slowly there is the realization that total dependency on hydrocarbon fuels is not a viable economic option. Proton exchange membrane fuel cells have a part in securing energy security for the country, improving the environment, greatly reducing urban pollution, and creating jobs in manufacturing as the technology advances. They can also provide a cost-effective and performance-driven rival for advanced batteries.
This study analyzes components of the PEM fuel cell, a technology offering the promise of greatly reduced environmental impact and excellent performance, price, and efficiency advantages. Recent historic developments and approaches are described along with recent commercial developments and the state of the art. Hydrogen feed fuel cells are based on the electrochemical reaction between hydrogen and oxygen. This electrochemical process does not pollute the environment with hydrocarbons, particulates or any sulfur or nitrogen oxides. The study identifies the opportunities and technological requirements of the proton exchange membrane fuel cell and the MEA and the bipolar plates for the PEM fuel cell. When several units of the membrane electrode assembly are capped off with a bipolar plate and properly assembled, the arrangement is referred to as a stack.
Questions to be answered include determining a timetable for PEM fuel cell commercialization, as well as what types of membranes and membrane assemblies are needed to make this possible.
INTENDED AUDIENCE
This report is intended to provide a unique analysis of the broadly defined global proton exchange membrane market and will be of interest to a variety of current and potential fuel cell users as well as fuel cell makers and component and membrane makers. This report also can provide valuable information in terms of assessing investment in particular technologies and, therefore, should benefit investors directly or indirectly. The vital importance of platinum as a catalyst for PEM fuel cells is addressed. Anyone interested in the precious metals market, in nanomaterials, or in alternative catalysts will find the evaluations of the technology of interest. BCC Research wishes to thank those companies, government agencies, and university researchers that contributed information for this report.
This analysis is designed to be as comprehensive as possible. This document is intended to be value to a broad audience of business, technical, investment, and regulatory professionals. It is an information source for an emerging industry as well as a reference on a developing technology. It presents analysis and forward-thinking evaluations that will be of advantage to manufacturers; material suppliers; and to local, state, and federal government entities. Corporate planners will benefit from the report’s evaluation of the demands for proton exchange membranes, membrane electrode assemblies, and platinum catalyst and the companies involved in their development and manufacture. Others may find the broad discussions of energy policy, environmental impact, platinum supply, and chemical synthesis of membranes to be of considerable value in understanding the opportunities and problems facing the fuel cell industry in the near- to mid-term.
SCOPE OF REPORT
The fuel cell industry in various forms has been developing for decades. There are notable examples of fuel cell successes. The proton exchange membrane fuel cell is emerging as a winner in many of the primary categories that fuel cells can satisfy. Existing membranes and assemblies still have room for improvement. Proton exchange membrane fuel cell development and commercialization is an ever-changing process. This BCC Research analysis examines the market and technology for the materials and technology of proton exchange membranes and electrode assemblies and for bipolar plates for PEMFCs, including direct methanol fuel cells (DMFCs). This includes the gas diffusion layer (GDL), the catalyst ink/electrode, the membrane itself, and the bipolar plate. Ancillary stack assembly materials such as bolts, gaskets, tie-outs, and final assembly and packaging costs are excluded.
This report details the actuals for 2006, 2009, and 2010 and compound annual growth rate (CAGR) projections for 2015 for the North American, European, Far Eastern, and rest-of-world markets. Selected 2006 actuals will help as a basis for today’s markets and tomorrow’s projections. When appropriate, consensus, optimistic, and pessimistic scenarios are presented. A patent analysis and discussion for power sources and vehicle components describes where research is performed and emphasizes intellectual property issues.
METHODOLOGY
An in-depth analysis of technical and business literature and published dissertations, a review of the history of the technologies involved, interviews with industry experts, company representatives, federal government researchers, and university scientists provide an assessment of the outlook for the next generation of PEMFCs and membrane electrode assemblies.

Historic markets (2006 and 2009) and the projected market for 2015 are provided. Most market summaries are based on a consensus scenario that assumes no unanticipated technical advances and no unexpected legislation. When appropriate, pessimistic, consensus, and optimistic market scenarios characterize several developmental markets. Totals are rounded to the nearest million dollars. When appropriate, information from previously published sources is identified to allow a more detailed examination by clients.
