Abstract: An illustrative example fuel cell device includes a cell stack assembly of a plurality of fuel cells that each include an anode and a cathode. A pressure plate is situated near one end of the cell stack assembly. An intermediate component is situated between the end of the cell stack assembly and the pressure plate. The intermediate component includes a porous material in at least two fluid reservoirs and a barrier between the two fluid reservoirs to prevent fluid communication between the reservoirs.

Abstract: An illustrative example fuel cell cooler plate includes a first side configured to be received adjacent a fuel cell component and a second side facing opposite the first side. The first side defines a first surface area of the plate. An edge is transverse to the first side and the second side. The edge has a surface area that is less than the first surface area. A first coolant passage within the plate is closer to the second side than the first side. A second coolant passage is between the first side and the first coolant passage. The second coolant passage is in a heat exchange relationship with the first coolant passage.

Abstract: An illustrative example fuel cell device includes a cell stack assembly of a plurality of fuel cells that each include an anode and a cathode. A pressure plate is situated near one end of the cell stack assembly. A spacer between the end of the cell stack assembly and the pressure plate has a length, a width, and a height. The height of the spacer defines a spacing between the pressure plate and the end of the cell stack assembly. The spacer has a plurality of ribs that define at least two fluid reservoirs. At least one of the ribs separates the fluid reservoirs so that fluid in one of the reservoirs is isolated from fluid in the other.
