1. An electrochemical conversion system comprising:

  • a housing defining a chamber and an opening therein allowing fluid communication between said chamber and ambience;

    a mass of hydrogen absorbent material positioned within said chamber;

    an electrochemical cell mounted to said housing opening which allows the passage of hydrogen protons;

    an electric circuit coupled to said electrochemical cell, said electric circuit having a load and a battery coupled in series with said load, and a supply of hydrogen;

    whereby changes in ambient temperature or pressure causes variations in the voltage of the electrochemical cell, whereby a difference in the state of charge between the electrochemical cell and the battery causes an electric current through the load.
