PURPOSE:To keep an atmosphere of a gas chamber dry with a moisture absorber when a cell is stopped and regenerating the absorber with heat generated in the cell by arranging a dryer containing moisture absorber and a fuel cell main body in a sealable container. CONSTITUTION:A fuel cell main body 2 and a dryer 4 containing moisture absorber 3 are arranged in a sealable and pressure resistant container 1. Temperature of a fuel cell 2 is raised with a supporting power source 22, and power generation is initiated at 500-650 deg.C by combining with heat generation of the fuel cell 2. When power generation is stopped, each of valves 13, 14, 18, 19, and 24 is directly closed, or after replacing hydrogen gas with an inactive gas, each of valves is closed. When temperature in a container falls near room temperature, moisture contained in air in the container is absorbed in the moisture absorber 3 in the dryer, and moisture in the container is decreased with time elapsed. The moisture absorbed in the absorber is exhaust from an exhausting pipe 23 with heat in power generation. |
