1. A power generator comprising:

  • a hydrogen producing fuel comprising a chemical hydride, an alkali intermetallic compound, or a combination thereof that generates hydrogen when exposed to water vapor;

    a fuel cell having a proton exchange membrane separating the hydrogen producing fuel from ambient; and

    a metal hydride hydrogen storage element, that absorbs and desorbs hydrogen;

    wherein a hydrogen permeable particulate filter is disposed between the chemical hydride alkali intermetallic compound, or combination thereof hydrogen producing fuel and the metal hydride hydrogen storage element; and

    wherein the electrical power generator is waterless such that the water molecules produced at the fuel cell as a byproduct of the reaction of hydrogen and oxygen are passively diffused from the fuel cell as water vapor to a fuel chamber that contains the chemical hydride, alkali intermetallic compound, or combination thereof hydrogen producing fuel where the water vapor reacts with the hydrogen producing fuel to generate hydrogen.
