    摘要： A fuel cell stack assembly comprises a plurality of fuel cells in a stack, the stack defining two opposing parallel end faces. An end plate is disposed at each opposing end face of the stack. Each end plate defines a compression surface adjacent to and in compressive relationship with a respective one of the two opposing parallel end faces. A coupling mechanism is attached to the end plates to thereby maintain the fuel cells in the stack under compression. At least one, preferably both, of the end plates comprise a preformed element defining the compression surface, the preformed element being configured with a predetermined curvature such that the compression surface is a convex surface when the preformed element is not under load whereas, under the application of the load to maintain the fuel cells under compression, flexure of the preformed element between elements of the coupling mechanism causes the compression surface to become a substantially planar surface. This provides uniform pressure distribution across the end faces of the fuel cell stack using fewer and lighter weight components.

    摘要： A single monolithic ceramic substrate has rectangular dimensions with thermal expansion dominant along the length. An inactive ceramic portion substantially surrounds a fuel cell active portion of scalable power. The active portion comprises a plurality of three-layer active structures, each including an electrolyte disposed between a first polarity electrode and a second polarity electrode, the electrolyte layers being co-fired with the inactive ceramic portion, and a first or second gas passage respectively associated with each first and second polarity electrode. The plurality of active structures are stacked in the thickness dimension with alternating polarity such that first polarity electrodes of adjacent active structures face each other with the associated first gas passage shared therebetween and second polarity electrodes of adjacent active structures face each other with the associated second gas passage shared therebetween. The power is scalable according to the number of active structures stacked to define the plurality.

    摘要： Provided is a solid polymer electrolyte type fuel cell having high durability. The fuel cell comprises a stack of single cell modules, each including an electrolyte membrane-electrode-frame assembly and a pair of separators. The electrolyte membrane-electrode-frame assembly includes a catalyst layer-attached electrolyte membrane having a polymer electrolyte membrane, an anode catalyst, and a cathode catalyst, a frame that is disposed at a peripheral portion of the catalyst layer-attached electrolyte membrane and has a rectangular inner periphery, and a pair of gas diffusion layers that are disposed on both surfaces of the catalyst layer-attached electrolyte membrane. The gas diffusion layers were disposed to cover an inner peripheral portion of the frame, respectively. A thickness of at least a part of a corner portion of the inner peripheral portion is smaller than a thickness of a linear side portion of the inner peripheral portion of the frame.
