Abstract
A fuel cell including an anode side including an anode, an anode side gas diffusion layer and an anode side bipolar plate formed of a first metal material, and a cathode side including a cathode, a cathode side gas diffusion layer and a cathode side bipolar plate formed of a second metal material. The fuel cell also includes a membrane having first and second sides positioned between the anode and cathode sides. The fuel cell further includes an intercalation host situated in the anode and/or cathode sides. The intercalation host is configured to intercalate metal ions formed from the first and/or second metal materials.
