Abstract

See full text

A composite electrolyte membrane (10) for a fuel cell (30) includes an ionomer component (16) extending continuously between opposed first and second contact surfaces (12, 14) defined by the membrane (10). The ionomer component is a hydrated nanoporous ionomer consisting of a cation exchange resin. The membrane (10) also includes a microporous region (18) consisting of the ionomer compound (16) and a structural matrix (20) dispersed through region (18) within the ionomer compound (16) to define open pores having a diameter of between 0.3 and 1.0 microns. The microporous region (18) does not extend between the contact surfaces (12, 14), and facilitates water management between the electrode catalysts (32, 34).
