High-temperature fuel cell with nickel grid, and high-temperature fuel cell stack

摘要

A nickel grid is arranged on the fuel-gas side of the high-temperature fuel cell, between the bipolar plate and the solid electrolyte. In order to avoid contact problems as the period of operation increases, the bipolar plate is provided with a nickel layer. The nickel grid is secured to the nickel layer in an electrically conducting manner, such as by spot welding.
