Electrical connection material for solid oxide fuel cell, solid oxide fuel cell, solid oxide fuel cell module, and method for manufacturing solid oxide fuel cell

摘要

An electrical connection material for solid oxide fuel cells, which is capable of preferred electrical connections. The electrical connection material includes a burn-out material-containing ceramic layer and a burn-out material-free ceramic layer stacked on the burn-out material-containing ceramic layer. The burn-out material-containing ceramic layer contains a conductive ceramic and a burn-out material.
