ABSTRACT:
The invention provides a fuel cell incorporating a thermal management scheme and associated methods of operation. In one aspect, a fuel cell system includes a frame enclosing a fuel cell, a coolant flow circuit and a heat exchanger. The frame has at least one external panel mounted thereon to enclose the fuel cell, a coolant circuit and heat exchanger. The coolant flow circuit is adapted to circulate a coolant through the heat exchanger and across a surface of the fuel cell to provide heat transfer between the fuel cell and the heat exchanger. An inlet orifice and an outlet orifice are coupled to the frame and to the heat exchanger, and are adapted to provide an export flow circuit from the inlet orifice through the heat exchanger to the outlet orifice. An insulating material is fixed to a surface of the external panel.
