摘要： PROBLEM TO BE SOLVED: To provide a means of establishing an appropriate gas pressure according to the location of cells in a separator by increasing and equalizing the gas pressure in the passage and preventing a reverse flow of the gas for the purpose of high density and high output. SOLUTION: In the separator 201 of a fuel cell, a porous member 204 with small porosity is installed at an exit 203 of a gas passage part 200. Since gas is banked up in the vicinity of the exit of the separator passage, the pressure of the gas increases uniformly in the separator. Since the gas is discharged from the exit by pressure gradient formed in the porous member, the gas does not flow reversely in the porous member and enter the separator passage. Furthermore, the gas velocity in the separator passage becomes slow, the deterioration of moisture content of the electrolyte membrane can be prevented. Furthermore, in the fuel cell of a stack form in which a plurality of fuel battery cells are stacked up, the porosity and shape of the porous member are changed according to the location of the cells, thereby establishing an appropriate passage pressure for every cell.

摘要翻译：要解决的问题：提供一种通过增加和均衡通道中的气体压力并且为了高的目的而防止气体反向流动而根据细胞在分离器中的位置建立适当气体压力的方法密度高，产量高。解决方案：在燃料电池的隔板201中，具有小孔率的多孔构件204安装在气体通道部分200的出口203处。由于气体在隔离通道的出口附近堆积，气体的压力在分离器中均匀地增加。由于气体通过在多孔构件中形成的压力梯度从出口排出，所以气体不会在多孔构件中反向流动并进入分离器通道。此外，分离器通道中的气体速度变慢，可以防止电解质膜的水分含量的劣化。此外，在堆叠多个燃料电池单元的堆叠形式的燃料电池中，根据电池单元的位置改变多孔构件的孔隙率和形状，从而为每个电池单元建立适当的通过压力。版权所有（C）2009，JPO＆INPIT
