A high performance hydrogen/chlorine fuel cell for space power applications

Abstract This article discusses the proton-exchange membrane fuel cell (PEMFC) as a high power and energy density power source. The two systems H 2 /Cl 2 and H 2 /O 2 PEMFC systems were compared over a wide range of mission lifetimes. It has been shown that the development of a H 2 /Cl 2 PEMFC could yield a system with power and energy densities inherently greater than currently available in H 2 /O 2 PEMFC.
