摘要:
Disclosed herein is a flat-tubular solid oxide cell stack in which the pathway of chemical reactions is long and the temperature and flow rate of feed gas are maintained at uniform levels, thus the efficiency of electrical energy generation is increased when the cell stack is used as a fuel cell, and the purity of generated gas (hydrogen) is increased when the cell stack is used as a high-temperature electrolyzer.
