A system includes a fuel cell stack. A liquid coolant loop is coupled to provide coolant to the fuel cell stack. An expansion tank is coupled to the coolant loop and has an expansion tank inlet to couple to a fuel cell stack cathode inlet. An inlet check v...

A fuel cell stack comprises two of an interface plate, two or more of an air plate, two or more of a reaction cell, at least one of a fuel-air bipolar plate, and at least one of a fuel-coolant bipolar plate defining a cooling surface. The two of an interfa...

Proposed is a fuel cell system, including a fuel cell stack connected to an intake line and an exhaust line, an air compressor connected to the intake line, and a heat energy storage part provided between the fuel cell stack and the air compressor on the i...

A fuel cell system (100) includes a fuel cell (10), a fuel gas supply/exhaust portion (50, 60), an oxidant gas supply/exhaust portion (30, 40), a cooling portion (70), and a controller (20). The controller performs at least one of a transient increase cont...

A power generation system onboard an aircraft includes a fuel cell module configured to produce heat. A loop heat pipe module is coupled to the fuel cell module. The loop heat pipe module includes a first fluid that absorbs the heat from the fuel cell modu...
