    • The invention provides a fuel cell system that is free from troubles due to contaminant ions by controlling the concentration of contaminant ions in cooling water. The fuel cell system comprises a fuel cell stack and a means for controlling the cell temperature by circulating a liquid coolant in the fuel cell stack or bringing it in contact with the fuel cell stack, the fuel cell stack comprising a plurality of unit cells that are laid one upon another, each of the unit cells comprising a hydrogen ion-conductive electrolyte membrane, a pair of gas diffusion electrodes which sandwich the electrolyte membrane, an anode-side conductive separator plate having a gas flow path for supplying a fuel gas to one of the electrodes, and a cathode-side conductive separator plate having a gas flow path for supplying an oxidant gas to the other of the electrodes, wherein a material adsorbing or absorbing ions is provided on a portion of the fuel cell system to come in contact with the liquid coolant.
    • 本发明提供了一种燃料电池系统,其通过控制冷却水中污染物离子的浓度而不会由于污染物离子而引起的麻烦。 燃料电池系统包括燃料电池堆和用于通过使燃料电池堆中的液体冷却剂循环或使其与燃料电池堆接触来控制电池温度的装置,该燃料电池堆包括多个单电池, 彼此叠置,每个单电池包括氢离子传导电解质膜,一对夹着电解质膜的气体扩散电极,具有用于将燃料气体供应到一个的气体流路的阳极侧导电隔板 以及阴极侧导电性隔板,其具有用于将氧化剂气体供给到另一个电极的气体流路,其中吸附或吸收离子的材料设置在燃料电池系统的一部分上以接触 与液体冷却剂。
