Patent ID: 7160639

Claim:
A engine comprising: a first electrochemical cell having a first ion conductive material, a first electrode mounted upon one side of said first ion conductive material, and a second electrode mounted upon one side of said first ion conductive material opposite said first electrode; a second electrochemical cell having a second ion conductive material, a third electrode mounted upon one side of said second ion conductive material, and a fourth electrode mounted upon one side of said second ion conductive material opposite said third electrode; a conduit system having a first conduit and a second conduit, said first conduit having one end in fluid communication with said first electrochemical cell second electrode and a second end in fluid communication with said second electrochemical cell third electrode, said second conduit having one end in fluid communication with said second electrochemical cell fourth electrode and a second end in fluid communication with said first electrochemical cell first electrode; heating means for transferring heat to said second electrochemical cell; cooling means for transferring heat from said first electrochemical cell; and a supply of ionizable gas contained within said conduit system, whereby with the passage of a current through the first electrochemical cell the ionizable gas is forced through the first electrochemical cell thereby increasing the pressure within the first conduit while simultaneously decreasing the pressure within the second conduit, and whereby the resulting pressure differential between the first conduit and the second conduit causes the ionizable gas to pass through the second electrochemical cell thus creating an electric potential difference between its first and second electrodes.
