PURPOSE:To obtain a substrate whose porosity is high, active material filling capability is good, and shape holding capability is good by sintering a nickel fiber aggregate and a porous nickel plate. CONSTITUTION:A nickel fiber aggregate 3 and a porous nickel plate 4 are sintered. Nickel fiber manufactured by stick-slip vibration are preferable as raw material in terms of less oxide film. 25-40mm long nickel fibers are preferable since they are easily formed in a sheet before sintering. The porous nickel plate 4 sandwiched between nickel fiber aggregates 3 is put in a sintering container 1 and a heavy cover 2 is put on the container 1. A substrate having high porosity and good shape holding capability can be obtained. |
