摘要： The present invention provides a gasketed fuel cell membrane electrode assembly comprising a polymer electrolyte membrane; layers of anode and cathode catalyst; anode-side and cathode-side fluid transport layer; and anode-side and cathode-side gaskets; where the gaskets comprise an elastomeric gasket material which is impregnated into the outer edge portions of the respective fluid transport layer; and where at least a portion of the contact face of each gasket bears a raised-ridge microstructured contact pattern. The gasketed fuel cell membrane electrode assembly according to the present invention may additionally comprise a rigid, non-elastomeric anode-side and cathode-side shims positioned between at least a portion of the gasket and the polymer electrolyte membrane. The raised-ridge microstructured contact pattern preferably comprises ridges which meet at joining point. Such raised-ridge microstructured contact patterns may be hexagonal patterns or degenerate hexagonal patterns. In another aspect, the present invention provides a method of making a gasketed fuel cell membrane electrode assembly by simultaneously binding together the parts of the MEA, impregnating uncured elastomeric gasket material into the outer edge portions of each fluid transport layer, and substantially curing the uncured elastomeric gasket material so as to form anode-side and cathode-side gaskets. In order to form a raised-ridge microstructured contact pattern on the contact face of each gasket, patterning plates bearing a negative relief of a raised-ridge microstructured contact pattern may be positioned between the press platens and the uncured elastomeric gasket material.

摘要： A method is provided for making a reinforced polymer electrolyte membrane, such as may be used in electrolytic cells such as fuel cells, by mixing a sulfonate- or sulfonyl halide-functional polymer with a bisamidine compound and subsequently trimerizing the amidine groups of the bisamidine compound to form triazine linkages. The sulfonyl halide or sulfonate groups may then be converted to sulfonic acid groups, yielding a polymer electrolyte reinforced with a polytriazine.

摘要： Shaped microporous articles are produced from polyvinylidene fluoride (PVDF) and nucleating agents using thermally induced phase separation (TIPS) processes. The shaped microporous article is oriented in at least one direction at a stretch ratio of at least approximately 1.1 to 1.0. The shaped article may also comprise a diluent, glyceryl triacetate. The shaped microporous article may also have the micropores filled with a sufficient quantity of ion conducting electrolyte to allow the membrane to function as an ion conductive membrane. The method of making a microporous article comprises the steps of melt blending polyvinylidene fluoride, nucleating agent and glyceryl triacetate; forming a shaped article of the mixture; cooling the shaped article to cause crystallization of the polyvinylidene fluoride and phase separation of the polyvinylidene fluoride and glyceryl triacetate; and stretching the shaped article in at least one direction at a stretch ratio of at least approximately 1.1 to 1.0.
