Membrane electrode assemblies for polymer electrolyte membrane fuel cells
K. Scott, Newcastle University, UK
Abstract:
Polymer electrolyte membrane fuel cells (PEMFCs) using hydrogen are attractive for certain mobile and portable applications and especially as a prime motive power for automobiles and other forms of transport. They can generate high electrical power densities, in excess of 1.0 W/cm2 of cross-sectional area, and high current densities (>> 1 kA/cm2) at relatively high efficiency greater than 50%. Performance of the fuel cell is primarily determined by the design of the membrane electrode assembly (MEA) and the choice of materials for its manufacture. This review considers different types of polymer membrane fuel cell ...
