PURPOSE: Zinc-air fuel cell system is provided to prevent overcharging and self discharging according to oxidation of external air and zinc balls, and to prevent excessive zinc ball oxidation and electrolyte consumption, thereby having relatively long effective operation time. CONSTITUTION: Zinc-air fuel cell system comprises: a case(26); a negative electrode bags(14) in the case, with acceptance space(12) in which zinc balls and electrolyte is accepted; a current collector(16), which is arranged inside the negative electrode bags, current-collecting electrons generated through reaction of zinc balls and oxygen in external air; and an air outflow line(32) exhausting inside air to outside according to charging rate of the system by being connected to the case, in case the charging rate of the system exceeds specific level. |
