A solid oxide fuel cell with intrinsic energy storage. The solid oxide
fuel cell includes a hydrogen electrode utilizing a modified anode active
material. The modified anode active material allows for intrinsic energy
storage within the hydrogen electrode which provides for transient
response, load leveling applications, a decreased start-up time, and
ability to accept charge. The solid oxide fuel cell may also include a
modified cathode active material that allows for intrinsic energy storage
within the oxygen electrode.
