Title: Fuel cell system including sacrificial nickel source

Abstract

In some examples, solid oxide fuel cell system comprising a solid oxide fuel cell including an anode, an anode conductor layer, a cathode, a cathode conductor layer, and electrolyte, wherein the anode and the anode conductor layer each comprise nickel; and a sacrificial nickel source separate from that of the anode and anode conductor layer, wherein the sacrificial nickel source is configured to reduce the loss or migration of the nickel of the anode and/or the anode current collector in the fuel cell during operation.
