PURPOSE:To strengthen bonding strength between nickel powers and manufacture an electrode capable of strongly resisting compressed deformation. CONSTITUTION:A very small amount of fine grains of pulverized aluminum intermetallic compound 4 is added to nickel powder 1 as a reinforcement, and mixed at a mixing process I. A binder 5 is added to a mixture, thereby providing slurry 6. This slurry 6 is molded into a tape form at a tape molding process II. Thereafter, the molded product of tape form is baked at high temperature at a baking process III. As a result, the compound 4 is eluted in the nickel powder 1, and the high temperature resistance of nickel itself increases. Thus, an electrode 7 capable of strongly resisting compressed deformation during cell operation can be provided. |
