<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel battery with a simple structure and low cost which can be miniaturized and capable of generating an equal power with each unit cell by preventing water droplets from entering a gas flow path for reaction gas circulation to choke the flow path and making flow of the reaction gas uniform. <P>SOLUTION: The fuel battery 20 is made by forming a laminated body with a number of cells composed of air electrodes, solid polymer electrolyte films and fuel electrodes each through a pair of separators 10 of a structure in which reaction gas flows from a top face downward through a gas flow path 8. The laminated body is provided with a supply manifold I for distributing the reaction gas to the cells, in which, a partitioning plate 22 with a size large enough to cover the gas flow path 8 is fitted at an upper part of the gas flow path 8, and a drain rest 24 for receiving droplets falling from an end part of the partitioning plate after condensation and droplets falling after being condensed on an inside wall face of the supply manifold I is fitted at a lower part of the partitioning plate 22, and at the same time, a gas supply port J for the supply manifold I is fitted at an upper part of the partitioning plate 22. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
