Abstract:
An electrochemical conversion system to be worn upon the skin of an animal, the system comprising:a first mass of hydrogen absorbent material; a second mass of hydrogen absorbent material spaced from said first mass of hydrogen absorbent material; a first electrode; a second electrode; a proton conductive membrane positioned between said first electrode and said second electrode, said first electrode, second electrode and said proton conductive membrane being operably between said first mass of hydrogen absorbent material and said second mass of hydrogen absorbent material; a housing containing said first mass of hydrogen absorbent material, said second mass of hydrogen absorbent material, said first electrode, said second electrode and said proton conductive membrane, said housing having a first chamber containing said first mass of hydrogen absorbent material and adapted to thermally transfer heat between said first mass of hydrogen absorbent material and the skin of an animal wearing the electrochemical conversion system, said housing also having a second chamber containing said second mass of hydrogen absorbent material adapted to thermally transfer heat to ambience; a supply of hydrogen; and mounting means for mounting said housing to the skin of an animal, whereby the first and second masses of hydrogen absorbent material are in fluid communication with each other through the first and second electrodes and through the proton conductive membrane and whereby the hydrogen may be desorbed by one mass of hydrogen absorbent material and absorbed by the other mass of hydrogen absorbent material while passing past and reacting with the electrodes and the proton conductive membrane so as to cause an electric potential difference between the first and second electrodes.
