摘要： The present technology relates to apparatus and methods for providing contact pressure distribution between fuel cell components in a fuel cell stack. In some embodiments, the technology relates to fuel cell flow field plate designs and to compression systems for fuel cell stacks that can be used, separately or in combination, to provide more uniform contact pressure distribution across the active area of fuel cells in a fuel cell stack.

摘要： An electrolyzer or unitized regenerative fuel cell has a flow field with at least one channel, wherein the cross-sectional area of the channel varies along at least a portion of the channel length. In some embodiments the channel width decreases along at least a portion of the length of the channel according to a natural exponential function. The use of this type of improved flow field channel can improve performance and efficiency of operation of the electrolyzer device.

摘要： Fuel cell assemblies comprising at least one thermally compensated coolant channel are provided. The thermally compensated coolant channel has a cross-sectional area that decreases in the coolant flow direction along at least a portion of the channel length. In some embodiments, such thermally compensated coolant channels can be used to provide substantially uniform heat flux, and substantially isothermal conditions, in fuel cells operating with substantially uniform current density.

摘要： A fuel cell power module includes a cylindrical housing encasing a fuel cell stack and an air supply. The housing has a major interior surface. The fuel cell stack can be cylindrical or hexagonal, and comprises fuel cells having an anode and an anode flow field plate, a cathode and a cathode flow field plate, and a membrane electrolyte interposed between the anode and the cathode. The air supply is directed to the plurality of fuel cell cathode flow field plates via a plenum defined by a space between the fuel cell stack and the housing major interior surface. The hexagonal fuel cell stack can be formed by a plurality of fuel cell groups shaped such that when aligned the fuel cell groups together constitute the hexagonal fuel cell stack.
