TERMINAL PLATE FOR FUEL CELL, MANUFACTURING METHOD OF TERMINAL PLATE FOR FUEL CELL, AND FUEL CELL (AS AMENDED)

摘要

A terminal plate 160F is configured such that an electrically conductive aluminum core plate 181 having a current collector terminal 161 is placed between a titanium cell-side plate 182 and a titanium end plate-side plate 183 both having higher corrosion resistance. Both the cell-side plate 182 and the end plate-side plate 183 have plate outer peripheries extended more outward than the outer periphery of the core plate 181. A plate adhesive seal member 184 is arranged to cover the outer peripheries of the respective plates including the core plate 181 and keep the plate-sandwiched state. The core plate 181 has a gold-plated outer peripheral end face and is thereby in the non-bonded state with the plate adhesive seal member 184 on the outer peripheral end face.

主权项

1. A terminal plate for fuel cell, comprising:
a first metal plate being an electrically conductive and configured to have a terminal element; a second metal plate and a third metal plate having higher corrosion resistance than the first metal plate and placed on a surface and a rear face of the first metal plate, the second metal plate and the third metal plate having outer peripheral areas extended more outward than an outer periphery of the first metal plate; and an elastic seal member bonded with the outer peripheral areas of the second and the third metal plates to seal outer peripheries of the first, the second and the third metal plates.
