Polymer membranes are the heart of a proton exchange membrane (PEM) fuel cell, serving as the electrolyte to allow ion exchange and create current. Fuel cells can provide clean energy for the environment. Other benefits of using fuel cells include low temperature operation; clean, safe, quiet performance; high-energy efficiency; ease of operation and low maintenance. Unlike a battery, a fuel cell does not store energy. It uses an electrochemical process, converting energy from one form to another, and will continue to operate as long as fuel is fed to it.
Researchers continue to search for a membrane electrode assembly with low-hydrogen-gas crossover, high-carbon-monoxide tolerance, high-power density and low cost. Some of the same problems are faced in dealing with the ceramic membranes of the solid oxide fuel (SOFC). What are the best materials and which companies are developing them?
This business opportunity report investigates the development and utilization of membranes for fuel cells in the near to mid-term time frame. Market forecasts will be provided through 2008. It will cover materials associated with the membrane assembly and applications of PEM fuel cells and SOFCs, including transportation, portable and stationary uses.
