A fuel battery capable of stably supplying fuel to the fuel battery cells, improved in efficiency of power generation reaction, and excellent in output characteristic by preventing decrease of the internal pressure of the fuel container due to decrease of the liquid fuel during power generation and by ensuring substantial liquid feeding ability of the pump. The fuel battery (1) comprises a membrane-electrode assembly (2), a fuel supply mechanism (3), and an internal pressure adjusting mechanism (4). The membrane-electrode assembly (2) has a fuel electrode (13), an air electrode (16), and an electrolyte membrane (17) sandwiched between them. The fuel supply mechanism (3) has a fuel distribution mechanism (5) disposed near the fuel electrode (13) of the membrane/electrode assembly (2), a fuel containing unit (6), a passage (7) interconnecting them, and a pump (8) installed in the passage (7). The internal pressure adjusting mechanism (4) is used for introducing external air when the internal pressure of the fuel containing unit (6) decreases and is installed nearer to the fuel containing unit (6) than the pump (8) of the fuel supply mechanism (3).
