PURPOSE:To enable the good-yield easy manufacturing of a fuel electrode whose high porosity ratio can be maintained for a long period of time, by immersing a porous base in a solution, drying the base, and then setting it in a cell to enhance a metal out of the base during the operation of the cell. CONSTITUTION:A powder of only a first metal such as nickel and cobalt, as to which it is easy to control the size of each pore and the ratio of porosity, is sintered to produce a porous base of desired porosity ratio. The base is immersed in a solution containing a stabilizing agent and then dried so that fine grains of the agent uniformly cling to the surface of the base. The base is then treated with heat in a cell (650 deg.C) to cause the fuse-bonding reaction of the base and the stabilizing agent to uniformly progress. For that reason, the base does not crack or warp during the heat treatment in the cell. |
