摘要： A method is provided for making crosslinked acidic polymers useful as ion conductive membranes, such as crosslinked sulfonated polyether ketones, sulfonated polysulfones, sulfonated polystyrenes, and other acidic polymers, by crosslinking with a species which generates an acidic functionality. The crosslinker preferably binds to acid functions by conversion of acid groups to imide functionality, which, due to the acidity of the N-H bonds therein, compensate for the acidity lost by the occupation of the acid groups and thus preserve membrane conductivity while contributing to membrane strength and resistance to swelling.

A hard stop arrangement, in one configuration, is provided between the first and second flow field plates. The hard stop arrangement is dimensioned to limit compressive forces imparted to the MEA upon establishment of contact between the first and second flow field plates under pressure. A sealing arrangement is provided between the first and second flow field plates and peripheral to the MEA. The unitized fuel cell assembly is configured as a stand-alone fuel cell unit that can be used alone or in a stack of fuel cell units.
