摘要： 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.

摘要： An illustrative example fuel cell assembly includes at least one cooler and a plurality of fuel cells each having an anode and a cathode. Each of the anodes includes an anode flow plate configured to allow fuel to flow through the anode. The anode flow plates have a respective flow resistance that varies among at least some of the anodes based on a distance between the corresponding anode and the cooler.

摘要： 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.

摘要： An illustrative example enclosure includes a support frame having longitudinal beams and lateral channel members that define an outward facing flow passage. A first roof panel and a second roof panel respectively include lateral edges aligned with the channel members. The lateral edge of the first roof panel is situated adjacent the lateral edge of the second roof panel. An interface between the lateral edge of the first roof panel and the lateral edge of the second roof panel is situated above or within the flow passage of one of the channel members. At least one seal engages the first roof panel and the second roof panel. The seal is received in the flow passage of the channel member in sealing engagement with the channel member.

摘要： A stack (10) of fuel cells (11) is manufactured with barriers (32) to prevent migration of a liquid electrolyte (such as phosphoric acid) out of the cells (11). The barrier (32) is secured within a step (34) formed within a land region (28) of a separator plate assembly (18) and extends from an edge (30) of the separator plate assembly (18) all or a portion of a distance between the edge (30) and a flow channel (24) defined within the separator plate assembly (18). The barrier (32) also extends away from the edge (30) a distance of between 0.051 and about 2.0 millimeters (about 2 and about 80 mils. The barrier (32) includes a hydrophobic, polymeric film (36), a pressure sensitive adhesive (38) as an assembly aid, and a fluoroelastomer bonding agent (40).

摘要： The thermal profile of one or more fuel cells (10) cooled by coolant flowing in coolant flow passageways (30, 31, 33, 34, 37-41, 45-50) is tailored by providing selected material (65, 68) adjacent a portion (33b) of the coolant passageway; the selected material has a different thermal transfer characteristic than material surrounding other portions of the coolant passageway. The material may be more insulative or more conductive. The material may be wrapping (65), such as shrink wrap, about a coolant tube, or it may be altered material (68) in a molding material.

摘要： An illustrative example electrical power generating system includes a fuel cell power plant that is configured to generate electrical power. The fuel cell power plant includes a cell stack assembly including a plurality of fuel cells that are configured to generate electrical power based on a chemical reaction. A coolant network is configured to carry fluid toward the cell stack assembly where fluid in the coolant network can become heated by absorbing heat from the fuel cell power plant. The coolant network includes a thermal hydraulic engine that is configured to generate electrical power. The coolant network is configured to carry the heated fluid to the thermal hydraulic engine where the heated fluid can be used for generating electrical power. The coolant network is configured to carry a reduced temperature fluid from the thermal hydraulic engine back toward the cell stack assembly.

摘要： An end-cooler assembly for a fuel cell includes a cooler having a coolant tube array. A composite material includes flake graphite and hydrophobic polymer. The composite material surrounds the coolant tube array and provides a first side. A flow field is formed in the first side. A thermal dam is embedded in and is entirely surrounded by the composite material. The thermal dam is arranged between the coolant tube array and the flow field. The coolant tube array, composite material, flow field and thermal dam comprise a unitary, monolithic structure bound together by the composite material.
