Metal-air Fuel Cell (Ultracell)

Ethanol-KOH metal-air fuel cell with 0.8-1.3V cell voltages, continuous metal feed fuel cell engine, energy storage ratings 1.3-9.0 kWh/kg. Two-cell total voltage 2.5V continuous current 10mA. Hydrogen infused in the metal electrode gives 0.5V voltage in the range of hydrogen fuel cell voltage up to 0.7V. Iron gives 0.8V cell voltage. A thin metal film spool with a separator sheet as a single use fuel pod would be the best, which can be lifted off the fuel cell electrolyte and replaced completely as mechanical recharge.
