Abstract
An electrochemical heat exchanger which includes a housing, hydrogen producing/consuming portions separated by a proton exchange membrane and a gas space designed to contact an object in need of cooling. The gas space includes either hydrogen or a liquid gas which is placed in thermal contact with an item to be cooled. The hydrogen gas or liquid coolant exchanges heat with the element to be cooled and is constantly replenished by hydrogen or liquid coolant forced through the heat exchanger by a pressure differential created between the respective hydrogen electrodes.
