Publication number: 20230083155Abstract: A fuel cell anode flow field includes at least one flow channel with a cross-sectional area that varies along at least a portion of its length. In some embodiments, the channel width decreases along at least a portion of the channel length according to a natural exponential function. This type of anode flow field can improve performance, reduce fuel consumption and/or reduce detrimental effects such as carbon corrosion and catalyst degradation, thereby improving fuel cell longevity and durability. When operating the fuel cell on either a substantially pure or a dilute fuel stream, this type of anode flow field can provide more uniform current density. These flow channels can be incorporated into reactant flow field plates, fuel cells and fuel cell stacks.Type: ApplicationFiled: September 21, 2022Publication date: March 16, 2023Inventors: David E. Leger, Greg J. Montie

Publication number: 20200328432Abstract: 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.Type: ApplicationFiled: June 29, 2020Publication date: October 15, 2020Inventors: David E. Leger, Matthew P. Paone, Greg J. Montie, Sean MacKinnon, Raoul Kingma
