REPORT SCOPE
INTRODUCTION
Fuel cells are viewed as potential candidates for auxiliary power, mobile power, stationary distributed, or central power for the global market as well as the power source for the transportation industry. 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. PEM 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.
This study analyzes components of the PEM fuel cell, a technology offering the promise of greatly reduced environmental impact and excellent - fuel efficiency. 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 when the PEM fuel cell will become a reality across the broad spectrum of all its potential commercial applications, and what types of membranes are needed to make this possible. There will eventually be a consolidation of the industry, but it is not yet clear when this will take place. The pace and path of various proton exchange membranes in development will impact the development of other types of fuel cells, and become a key factor in the maturation of the industry as a whole. The commercialization of fuel cells will create demand for new products and services from many diverse industries, which will in turn likely create a positive impact on the U.S. and, eventually, the global, economy.
SCOPE OF STUDY
This report:
- Focuses on the electrolytes of polymer membranes; the heart of the proton exchange membrane (PEM) fuel cell.
- Examines the advancing technology of these membranes, the membrane electrode assembly (MEA) and the bipolar plates.
- Reviews the companies involved in these developments, the current and projected incentives, and the projected markets for such technologies.
- Identifies the applications of the PEM fuel cell as a power source for transportation, stationary distributive power, and small-scale applications such as portable electronic devices.
- Identifies how researchers are solving the search for better membranes that have greater tolerances to poisoning, greater durability, and lower costs.
- Underlines the fact that commercialization of fuel cells is not solely influenced by engineers and scientists working on stacks and reformers, but how the major cost issue of the catalyst component is addressed.
METHODOLOGY AND INFORMATION SOURCES
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 PEMs and MEAs. Other information sources include product literature from suppliers, scientific references, conferences, patent searches, and BCC Research's monthly newsletters Fuel Cell Technology News, Battery and EV Technology News, and Membrane & Separation Technology News.
The report makes projections for market sectors in terms of 2006 constant dollars representing real growth. Historical values are presented for the given year. The market analyzed is for the United States, but attention is given to the global aspects of the membrane, the electrode assembly, and PEM fuel cell market.
