    • In a solid electrolyte fuel cell, reactant gases are directed by the reactant gas distributing means to flow radially between its central and peripheral portions and this obviates the need to provide an overall gas seal between the individual components of the fuel cell. A gas seal, if necessary at all, may be provided in selected areas. This permits the individual members of the fuel cell to freely slide with respect to one another during thermal expansion or contraction. The radial flow of reactant gas streams effectively reduces the travel path, and hence the concentration gradient, of the reactant gases. This contributes to the accomplishment of a solid electrolyte fuel cell having improved reliability and characteristics. As a further advantage, the discharged reactant gases may be burnt in a combustion chamber and a solid electrolyte fuel cell having a higher thermal efficiency can be realized by making use of the resulting heat of combustion.
    • 在固体电解质燃料电池中,反应物气体被反应物气体分配装置引导以在其中心部分和周边部分之间径向流动,这样就不需要在燃料电池的各个部件之间提供总的气体密封。 如果需要,可以在选定的区域提供气体密封。 这允许燃料电池的单个构件在热膨胀或收缩期间相对于彼此自由滑动。 反应气流的径向流有效地减少了反应气体的行进路径,并因此降低了浓度梯度。 这有助于实现具有改进的可靠性和特性的固体电解质燃料电池。 作为另一个优点,排出的反应物气体可以在燃烧室中燃烧,并且可以通过利用所产生的燃烧热来实现具有更高热效率的固体电解质燃料电池。

    • A solid electrolyte type fuel cell power generation system includes a power generation module, an inverter, and a control device. The module includes a stack chamber, a combustion chamber, and a heat exchanging chamber, partitioned one from the other by partition walls, are provided. The stack chamber has a cell stack, an oxidant gas exhaust chamber for collecting an oxidant gas exhausted from the cell stack, and a fuel gas exhaust chamber for collecting a fuel gas exhausted from the cell stack. The oxidant gas exhaust chamber and the fuel gas exhaust chamber are communicated through a first exhaust gas passage provided in the partition wall. In the combustion chamber, the exhaust oxidant and fuel gases which have passed through the first exhaust gas passage are burnt and the resulting combustion gas is introduced into the heat exchanging chamber through the second exhaust gas passage provided in the partition wall. The heat exchanging chamber has a heat exchanger and the fuel gas and the oxidant gas to be supplied to the cell stack are preheated, respectively.
    • 固体电解质型燃料电池发电系统包括发电模块,逆变器和控制装置。 该模块包括堆叠室,燃烧室和通过分隔壁彼此隔开的热交换室。 堆叠室具有电池堆,用于收集从电池堆排出的氧化剂气体的氧化剂气体排出室和用于收集从电池堆排出的燃料气体的燃料气体排出室。 氧化剂气体排出室和燃料气体排出室通过设置在隔壁中的第一排气通路连通。 在燃烧室中,已经通过第一废气通道的排气氧化剂和燃料气体被燃烧,并且所产生的燃烧气体通过设置在分隔壁中的第二排气通道引入热交换室。 热交换室具有热交换器,并且将要供给到电池堆的燃料气体和氧化剂气体分别预热。
