In polymer electrolyte membrane (PEM) fuel cells and electrolyzes, attaining and maintaining high membrane conductivity and durability is crucial for performance and efficiency. The use of low equivalent weight (EW) perfluorinated ionomers is one of the few options available to improve membrane conductivity. However, excessive dimensional changes of low EW ionomers upon application of wet/dry or freeze/thaw cycles yield catastrophic losses in membrane integrity. Incorporation of ionomers within porous, dimensionally-stable perforated polymer electrolyte membrane substrates provides improved PEM performance and longevity. The present invention provides novel methods using micromolds to fabricate the perforated polymer electrolyte membrane substrates. These novel methods using micromolds create uniform and well-defined pore structures. In addition, these novel methods using micromolds described herein may be used in batch or continuous processing.

The solid polymer electrolyte may also be deposited over the top and/or bottom surfaces of the support.

Universal cell frame generic for use as an anode frame and as a cathode frame in a water electrolyzer. According to one embodiment, the universal cell frame includes a unitary annular member having a central opening. Four trios of transverse openings are provided in the annular member, each trio being spaced apart by about 90 degrees. A plurality of internal radial passageways fluidly interconnect the central opening and each of the transverse openings of two diametrically-opposed trios of openings, the other two trios of openings lacking corresponding radial passageways. Sealing ribs are provided on the top and bottom surfaces of the annular member. The present invention is also directed at a water electrolyzer that includes two such cell frames, one being used as the anode frame and the other being used as the cathode frame, the cathode frame being rotated 90 degrees relative to the anode frame.

A direct liquid fuel cell is disclosed and wherein the fuel cell includes an anode fluid diffusion layer positioned adjacent to the anode side of the membrane electrode assembly, and which consists of, at least in part, a porous electrically conductive ceramic material which is substantially devoid of predetermined fluid passageways. A source of an aqueous hydrocarbon fuel solution is coupled in direct fluid flowing relation relative to the anode fluid diffusion layer, and the anode fluid diffusion layer substantially evenly distributes the aqueous hydrocarbon fuel solution across the active area surface of the anode side of the membrane electrode assembly.
A proton exchange membrane fuel cell is described and which includes a proton exchange membrane having at least one gas diffusion layer which is juxtaposed relative thereto, and which is fabricated, at least in part, of a porous, electrically conductive, inorganic material which is selected from the group comprising metal diborides, metal disilicides, metal nitrides, metal carbides, and composites, laminates and solid solutions thereof.
