| 摘要 |
A fuel cell unit (7) is placed in a cylindrical casing (1) of a fuel cell device (10) whose shape is simple and can be easily standardized. The fuel cell unit (7) comprises a cylindrical fuel electrode (2) arranged coaxially with the casing (1), a cylindrical electrolyte membrane (3) composed of a proton conductive solid polymer membrane which surrounds the outer periphery of the fuel electrode (2), a cylindrical air electrode (4) surrounding the outer periphery of the electrolyte membrane (3), and a fuel storage tank (5) for supplying a fuel to the fuel electrode (2) and a fuel recovery tank (6) for recovering the unreacted fuel from the fuel electrode (2) both arranged inside the fuel electrode (2). A positive electrode output terminal (8) is so formed as to protrude from the center of one end face of the casing (1), while a negative electrode output terminal (9) is arranged on the other end face. |
