摘要： A fuel cell stack comprising a plurality of serially-connected fuel cell stages, each stage comprising a plurality of fuel cells arranged electrically in parallel such that each stage has the voltage drop of a single fuel cell but current output defined by the total cell area. The assembled stack thus comprises essentially a plurality of internal fuel cell stacks arranged in parallel, each stack having the same voltage, and the stack currents being additive. The total voltage is the same as for a prior art stack of the same number of stages, but the current and hence the power output is multiplied over that of a single-cell stack by the number of internal fuel cell stacks. Preferably, each stage is a cassette including a plurality of windows for receiving the individual fuel cell units; a plurality of anode and cathode interconnects; and a single separator plate.

Exemplary application methods may include painting, rolling, screening, or extrusion dispensing. Brazing alloys in accordance with the invention are useful in bonding ceramics to ceramics, ceramics to metals, and metals to metals.

摘要： An improved SOFC repeating fuel cell unit comprising three flat plates and a cell retainer. The three flat plates are metallurgically joined (brazed or laser welded) into a subassembly to which is added the fuel cell and cell retainer (which may also be joined as a second subassembly). Each flat plate performs a specific set of functions and can be optimized for those functions. Since the plates are flat and designed to overlap in loaded areas, the fuel cell unit is not prone to dimensional collapse which eliminates the internal reinforcements of the prior art design. The cell retainer is formed to provide a self-locating and locking feature for the fuel cell and decouples thermal stresses from the thin ceramic fuel cell.
