Abstract
A liquid fuel battery is described, having a vented case, an internal fuel chamber, and a plurality of substantially planar vertically stacked battery elements having separated fuel-sides and air sides. Such sides are separated by a series of anodic and cathodic seals. In one embodiment, a cathode contains doped carbon nanofibers and may be treated with polytetrafluoroethylene or another hydrophobic material. An anode current collector and/or cathode current collector may contain perforated metal, including metal mesh. Battery elements may be U-shaped to maximize the efficiency of the air-fuel interaction. The cathode is active for oxygen reduction and inactive for fuel oxidation.
