Electricity-Generation Device

摘要

An electricity generation device includes: a tubular fuel cell (2) having an electrolyte layer (7) sandwiched between inside and outside electrodes (5, 6) to which a fuel gas is supplied, the fuel cell having an interior formed as an inside channel (3) for the fuel gas; a cover pipe (9) arranged around the fuel cell (2) with a gap provided between the outside electrode (6) and the cover pipe; a connecting member (13) connecting the fuel cell (2) and the cover pipe (9) to each other and permitting an outside channel (4) for the fuel gas to be formed around the fuel cell (2) by making use of the gap; and a fuel gas pipe (12) connected to each of opposite ends of the cover pipe (9) and forming a flow path for the fuel gas in cooperation with the cover pipe (9).
