Abstract: Fuelling progress Solid oxide fuel cells are not suitable for powering small portable devices, mainly because if built small, they need heat input to keep them running. A new approach to fuel-cell design tackles that problem head on, resulting in the first thermally self-sustaining miniature solid-oxide fuel cell. In this cell, the heat is from the oxidation reaction at the anode. Good power densities are achieved, and as proof of principle, the cell has successfully driven an MP3 player.
