    摘要: A method of manufacturing a fuel cell flow field plate is disclosed in which a generally even flow distribution across the flow field is provided. The method includes providing an inlet manifold in fluid communication with the flow field. The flow field includes multiple channels for which some of the channels receive restricted flow from the inlet manifold as compared to other channels. A relative pressure drop between the channels is altered with a pressure drop feature to encourage fluid flow from the inlet manifold to the channels with restricted flow, which results in a generally even flow distribution across the flow field.

    摘要: A method of manufacturing a porous structure for a fuel cell is disclosed. The method includes providing the porous structure, and processing the porous structure to selectively produce a non-porous region on the porous structure. In one example, the non-porous region is provided at the perimeter of the porous structure, an edge of an internal manifold and/or a surface or recess that supports a seal or gasket. The non-porous region has a porosity that is less than the porosity of the porous structure. The non-porous region prevents undesired leakage of fluid from the porous structure and prevents migration of adhesive associated with the seals.

    摘要: Fuel cell systems (10) and related methods for limiting fuel cell slippage are provided. A stacked plurality of adjacent fuel cells (14) collectively forming a fuel cell stack (12). The fuel cells each include a pair of first and second plates (30, 30′, 30″; 32, 32′, 32″) at respective opposite ends thereof. A first fuel cell has a first plate (30, 30′, 30″) in engagement with a second plate (32, 32′, 32″) of a second fuel cell adjacent to the first fuel cell. A slip mitigation arrangement (50, 50′, 50″) between at least one of the pairs of the first and second fuel cells comprises first and second seats (62, 62′, 62″; 64, 64′, 64″) recessed in the engagement surfaces of the first and second conductive plates respectively, and a key member (60, 60′, 60″) having opposite ends seated in the first and the second recessed seats such that relative movement between the first and the second fuel cells is limited.

    摘要: A PEM fuel cell assembly includes cooler plates (10) with internal coolant manifolds (25) isolated from the cell stack assembly by an isolation gap (28) to minimize the risk of contamination of the cells by antifreeze. The internal coolant manifolds are formed by seal assemblies (24), each disposed between inlet or outlet openings (14, 15) in projections (16) of each cooler plate extending outwardly from the fuel cell planform (20) to provide a gap (28), which may be used as an air turn manifold. Flanges (40) with through holes (41) may receive tie rods to assist assembly of a fuel cell stack with the cooler plate.
