NOVELTY - Making (I) polyphenylene sulfide membrane comprises: (a1) combining polyphenylene sulfide-containing resin (40) and water soluble carrier resin (42) to get resinous mixture (44); (a2) shaping resinous mixture to form shaped resinous mixture having polyphenylene sulfide-containing structures within carrier resin; (a3) contacting the mixture with water to separate polyphenylene sulfide-containing structures from carrier resin; (a4) optionally adding protogenic groups to polyphenylene sulfide-containing structures; and (a5) adding catalyst to polyphenylene sulfide-containing structures.    USE - The method is useful for making polyphenylene sulfide membrane which is useful in fuel cell (claimed).    ADVANTAGE - The method provides fuel cell in cost-effective manner.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) making (II) polyphenylene sulfide membrane, comprising: step (a1) as above per se; (b2) extruding the resinous mixture to form an extruded resinous mixture having polyphenylene sulfide-containing fibers (50) within the carrier resin; (b3) contacting the extruded resinous mixture with water to separate the polyphenylene sulfide-containing fibers from the carrier resin; (b4) sulfonating the polyphenylene sulfide-containing fibers; (b5) coating at least a portion of the polyphenylene sulfide-containing fibers with a catalyst; and (b6) forming the polyphenylene sulfide-containing fibers into a fuel cell electrode layer; and    (2) fuel cell comprising: first flow field plate; second flow field plate; first catalyst-containing electrode layer interposed between the first flow field plate and the second flow field plate; second catalyst-containing electrode layer interposed between the first flow field plate and the second flow field plate; and ion-conducting layer interposed between the first catalyst layer and the second catalyst layer, where the first catalyst-containing electrode layer and the second catalyst-containing electrode layer include sulfonated polyphenylene sulfide-containing fibers, and the sulfonated polyphenylene sulfide-containing fibers includes catalyst.
