Devices powered by fuel cells can be operated for extended durations when the fuel cells are adapted to extract the necessary reactants for generating power from the surrounding environment and when the concentration of reactants in that environment is maintained at a sufficient level by interaction between the environment and a reactant-enriched atmosphere.
