Patent number: 11462747Abstract: A hybrid bipolar plate assembly for a fuel cell includes a formed cathode half plate and a stamped metal anode half plate. The stamped metal anode half plate is unnested with and affixed to the formed cathode half plate. Each of the half plates has a reactant side and a coolant side, a feed region, and a header with a plurality of header apertures. The coolant side of the formed cathode half plate need not correspond with cathode flow channels formed on the opposite reactant side. The coolant side of the stamped metal anode half plate has lands corresponding with anode channels formed on the opposite oxidant side. The lands define a plurality of coolant channels on the coolant side of the stamped metal anode half plate and abut the coolant side of the formed cathode half plate.Type: GrantFiled: October 10, 2019Date of Patent: October 4, 2022Assignee: JIANGSU HORIZON NEW ENERGY TECHNOLOGIES CO.
