摘要： An anode effluent which is discharged from an anode (7) of a fuel-cell stack (1) is recirculated to the anode (7) by a recirculation passage (32, 35, 37), while a hydrogen cylinder (5) supplies hydrogen to the recirculation passage (32, 35,37). A hydrogen separator (2) separates hydrogen from a gas in the recirculation passage (32, 35, 37), and discharges the remaining gas after the hydrogen is separated to the atmosphere, whereby the hydrogen concentration in a hydrogen rich gas supplied to the anode (7) is raised. A controller (50) uses a valve (V1) to connect the recirculation passage (32, 35, 37) to the anode (7) directly or via the hydrogen separator (2), whereby the hydrogen concentration in the hydrogen rich gas is maintained in an appropriate range without discharging the hydrogen to the atmosphere.

摘要： A negative electrode for a secondary battery according to the present invention has a collector and a negative electrode active material layer formed on a surface of the collector and containing negative electrode active material particles. In the negative electrode active material layer, an insulating material is arranged between the negative electrode active material particles so as not to develop conductivity by a percolation path throughout the negative electrode active material layer. It is possible in this configuration to effectively prevent the occurrence of a short-circuit current due to an internal short circuit and the generation of heat due to such short-circuit current flow in the secondary battery while securing the battery performance of the secondary battery.

摘要翻译：本发明的二次电池用负极具有集电体和负极活性物质层，该层集电体和负极活性物质层形成在集电体的表面并含有负极活性物质粒子。在负极活性物质层中，在负极活性物质粒子之间设置绝缘材料，以便不会在整个负极活性物质层中通过渗透路径产生导电性。在这种配置中，可以有效地防止由于内部短路引起的短路电流的发生和由于二次电池中的这种短路电流而产生的热量，同时确保了二次电池的电池性能。
