<P>PROBLEM TO BE SOLVED: To provide technology to control deterioration of a reaction gas distribution and flow nature caused by fluctuation of pressure loss among each of the cells, in a fuel battery equipped with a plurality of single cells. <P>SOLUTION: A fuel battery system 1000 is equipped with a fuel battery 100 and a hydrogen supply portion 200. The fuel battery 100 is provided with a first and a second hydrogen manifolds 11, 12 for supply of hydrogen to each of the single cells 110, and the first and the second hydrogen manifolds are each provided with a first and a second valves 121, 122. Also, a joint portion of each single cell 110 with the second hydrogen manifold 12 is provided with a high pressure loss portion 30. The control portion of the fuel battery system 1000 switches a switching status of the first and the second valves 121, 122 alternatively, changing supply flow paths of hydrogen to supply hydrogen to the fuel battery 100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
