Sparse Matrix Factorization of Gene Expression Data
A fuel cell apparatus comprising a cell block and a oxygen-containing gas purifier placed by the side of cell block, a fuel recirculation circuit, an electrolyte recirculation circuit, a static device for oxygen-containing gas draft, fed through a fuel leakage circuit and a heat exchanger exchanging heat between the hot electrolyte issuing from the cell block and the cold oxygen-containing gas purifying liquid issuing from the oxygen-containing gas purifier, thereby causing the respective motions of the electrolyte and the purifying liquid by double thermosiphon effect.
