Abstract
Abstract In a fuel cell assembly, each cell is disposed inside a fuel flow passage (9) or a oxygen-containing gas flow passage (5). A lower end portion of the cell is inserted into a recess defined in a partition wall sectioning (8a) between the fuel flow passage or a fuel feed passage and the oxygen-containing gas feed passage, while an uppper end portion of the cell is insertible into and withdrawable from a further partition wall (8b) sectioning between the fuel flow passage or the oxygen-containing gas passage and an exhaust passage (15). In a further fuel cell assembly also disclosed, each cell is disposed inside a fuel flow passage or an oxygen-containing gas flow passage. One side end of the cell is airtightly connected with a partition wall sectioning between the fuel flow passage and the oxygen-containing gas feed passage or between the fuel feed passage and the oxygen-containing gas flow passage, while the other side end of the cell is insertible into and withdrawable from a further partition wall sectioning between the fuel flow passage or the oxygen-containing gas flow passage and the exhaust passage.
