摘要： A membrane-electrode assembly for electrochemical cells such as proton exchange membrane fuel cells and direct methanol fuel cells operating at ambient conditions are activated first by exposing them at a temperature higher than ambient temperature and with the gaseous reactants back-pressurized. The performance of the membrane-electrode assemblies, especially those whose electrodes are of low catalyst loadings made using supported catalysts, improves dramatically after the activation.

摘要： A reactant flow system for a proton exchange membrane (PEM), hydrogen-air, fuel cell stack, is described. The flow system includes the use of single-pass or multi-pass, flow channels. A flow channel section having at least one adjacent channel section whose reactant flows in an opposite direction thereto. The system has respective reactant inlets that are effectively adjacent to reactant outlets of the adjacent channel section. Restrictions are used at the reactant inlets to assure substantially uniform reactant flow among all of the flow channels. The PEM fuel cell stack has a mechanism for removing heat therefrom in order to prevent drying out of the electrolyte membrane.

摘要： A bipolar gas reactant distribution assembly for use in a fuel cell is disclosed, the assembly having a solid edge seal to prevent leakage of gaseous reactants wherein a pair of porous plates are provided with peripheral slits generally parallel to, and spaced apart from two edges of the plate, the slit being filled with a solid, fusible, gas impervious edge sealing compound. The plates are assembled with opposite faces adjacent one another with a layer of a fusible sealant material therebetween the slits in the individual plates being approximately perpendicular to one another. The plates are bonded to each other by the simultaneous application of heat and pressure to cause a redistribution of the sealant into the pores of the adjacent plate surfaces and to cause the edge sealing compound to flow and impregnate the region of the plates adjacent the slits and comingle with the sealant layer material to form a continuous layer of sealant along the edges of the assembled plates.
