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.
