Patent ID: 8535835

Claim:
A fuel cell module comprising: a housing container, a power generating chamber in the housing container; a cell stack in the power generating chamber comprising a plurality of column-shaped fuel cells comprising one or more internal gas flow channels therein, and arranged in an upright state and electrically connected, wherein, between a side portion of the fuel cells that constitute the cell stack along the arrangement direction of the fuel cells and an outer wall of the housing container facing the side portion, the housing container comprises: a first flow channel between the outer wall and a first wall located inside of the outer wall, operable to guide a reaction gas supplied from the lower side of the housing container to flow to the upper side; a second flow channel between a second wall located inside the first wall and a third wall located inside the second wall, operable to guide the reaction gas that has passed through the first flow channel and flowed into the upper side to flow to the lower side so as to be supplied to the power generating chamber; and a third flow channel between the first wall and the second wall operable to guide an exhaust gas in the power generating chamber to flow from the upper side to the lower side, the third flow channel formed between the first flow channel and the second flow channel, wherein the third flow channel and the second flow channel are separated only by the second wall.
