    • The present invention provides a fuel cell power generating system comprising a hydrogen generator (1) which generates hydrogen gas by allowing a source material to undergo a reforming reaction and a fuel cell (3) which is equipped with a fuel electrode and an air electrode and which generates electric power by allowing the hydrogen gas supplied to the fuel electrode and oxygen gas supplied to the air electrode to react electrochemically with each other. The fuel cell power generating system further comprises a water recovering portion (5) configured to recover water from water vapor discharged from at least one of the fuel and air electrodes, a water storing portion (6) which is equipped with a tank (6a) for storing water recovered by the water recovering portion (5), and a water supply portion (10) configured to supply water stored in the tank (6a) to the hydrogen generator (1), wherein the tank (6a) is configured, in order to prevent water stored in the tank (6a) from decaying, such that the stored water is dischargable to the outside, and wherein the fuel cell power generating system is so configured as to make a decision on whether or not to discharge the stored water to the outside for the prevention of water decay.

    • PROBLEM TO BE SOLVED: To make a stable carbon monoxide treatment capability exhibited even in the case where the use conditions are changed by forming a catalytic reaction part having a catalyst layer containing a platinum-group metal catalyst, a raw material gas supply part for supplying hydrogen containing carbon monoxide an auxiliary component, and a branched part joined to the catalytic reaction part. SOLUTION: A raw material gas generated in a raw material gas supply part 1 is supplied to a catalytic reaction part 3 through a raw material gas supply route 5. At that time, air from the oxidizing gas supply part 2 is supplied to the raw material gas through a joint 6. A part of the raw material gas is led to the upstream side of the catalyst body 3a in the catalytic reaction part 3 and the remaining is led to the downstream side of the catalyst body 3a through a branched route 8. The amounts of the raw material gas to led to the raw material gas supply route 5 and to the branched route 8 are controlled by a branching amount control part 7. The mixed gas is further led to another catalyst body 3b to remove carbon monoxide in the raw material gas by oxidation. After that, the raw material gas is supplied to a fuel cell main body from a raw material gas discharge route 9.
    • 要解决的问题:即使在通过形成具有含有铂族金属催化剂的催化剂层的催化反应部分来改变使用条件的情况下,即使表现出稳定的一氧化碳处理能力,也可以提供供给用的原料气体供给部 含有一氧化碳的辅助组分,和与催化反应部分接合的分支部分。 解决方案:原料气体供给部1中产生的原料气体通过原料气体供给路径5供给到催化反应部3.此时,来自氧化气体供给部2的空气被供给至原料气体供给部1。 气体通过接头6.原料气体的一部分被引导到催化反应部件3中的催化剂体3a的上游侧,其余的通过分支路线8被引导到催化剂体3a的下游侧。 通过分支量控制部7控制导入原料气体供给路径5和分支路径8的原料气体的量。将混合气体进一步导入另一个催化剂体3b,以除去 原料气通过氧化。 之后,原料气体从原料气体排出路径9供给到燃料电池主体。
