August 28, 2017. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3394032 3492161 Fuel cells Fuel cell system configurations Electrode system for a fuel or electrolysis cell arrangement Fuel cell stack Fuel cell battery with improved membrane cooling Novel fuel cell fluid flow field plate Fuel cell fluid flow field plate Coolant flow field plate for electrochemical fuel cells InventorApplicationNo. 919648 filed on 08/28/1997US Classes:429/34, Housing member, seal, spacer or fluid distributing or directing means429/35, Having sealing feature429/36, Having bonded seal, e.g., welded, adhesive, molded in situ, etc.429/39And fluid directing meansExaminersPrimary: Nuzzolillo, MariaAssistant: Crepeau, Jonathan Attorney, Agent or FirmInternational ClassesH01M 002/00H01M 002/08 H01M 002/14 H01M 008/00 AbstractA fluid flow plate includes first and second outward faces. Each of the outward faces has a flow channel thereon for carrying respective fluid. At least one of the fluids serves as reactant fluid for a fuel cell of a fuel cell assembly. One or more pockets are formed between the first and second outward faces for decreasing density of the fluid flow plate. A given flow channel can include one or more end sections and an intermediate section. An interposed member can be positioned between the outward faces at an interface between an intermediate section, of one of the outward faces, and an end section, of that outward face. The interposed member can serve to isolate the reactant fluid from the opposing outward face. The intermediate section(s) of flow channel(s) on an outward face are preferably formed as a folded expanse.Field of SearchFUEL CELL, SUBCOMBINATION THEREOF OR METHODS OF OPERATINGProcess of operating Having heat exchange means Housing member, seal, spacer or fluid distributing or directing means Having support or spacers with fluid distribution means And fluid directing means Having sealing feature Having bonded seal, e.g., welded, adhesive, molded in situ, etc. |
