摘要： A fuel cell corrugated current collector having successive spaced rows of corrugations, with the corrugations in a given row establishing successive peak and valley regions along the given row and the spaced rows of corrugations being adapted so that corresponding peak regions from row-to-row establish through passages for receiving and supporting solid catalyst elements. The spaced rows of corrugations are such that there is a given pitch between successive peak regions. The corrugations in the rows are also such that corresponding peak regions from row-to-row have a finite off-set which is less than 50 percent of the pitch. This establishes a plurality of through passages in the current collector each extending from row-to-row for receiving and supporting the solid catalyst elements. Also, the off-set is based on the catalyst dimensions and is set such that the corrugations engage the catalyst elements.

摘要： The design and method of fabrication of a three-dimensional, porous flow structure for use in a high differential pressure electrochemical cell is described. The flow structure is formed by compacting a highly porous metallic substrate and laminating at least one micro-porous material layer onto the compacted substrate. The flow structure provides void volume greater than about 55% and yield strength greater than about 12,000 psi. In one embodiment, the flow structure comprises a porosity gradient towards the electrolyte membrane, which helps in redistributing mechanical load from the electrolyte membrane throughout the structural elements of the open, porous flow structure, while simultaneously maintaining sufficient fluid permeability and electrical conductivity through the flow structure.

摘要： An end unit for a fuel cell stack is described that contains an integrated heat exchanger for superheating the fuel gas before delivery to the stack. Heat is transferred from the hot cathode outlet stream to the cool fuel inlet stream in a space adjacent the stack's end plate. The end unit is designed as a hollow box forming the shell of the exchanger with the heat exchanger inside. The end unit has openings that allow fuel cell process gas to be taken directly from the stack without requiring piping or ductwork to be attached to thin manifolds. Separate chambers are provided for both the cathode outlet and anode outlet gas, thereby allowing all process connections to be made at one end of the stack. The end unit also features a current collection post that is separated from the end cell of the stack by a multitude of members which provide structural support for the end unit and act to more uniformly collect electrical current than would a single, large current post.
