Abstract
An electrochemical heat exchanger including a housing, at least one electrochemical cell within the housing with a first electrode and a hydrogen electrode at least partially immersed in a liquid electrolyte, and positive and negative terminals of the electrochemical cell connected through the housing to respective positive and negative ends of a power supply. The housing includes a gas space which is in communication with a heat exchange chamber. The heat exchange chamber can be a flexible chamber capable of expanding in response to an increase in pressure in the electrochemical cell and contracting in response to a decrease in pressure in the electrochemical cell or it can be a conduit whereby an element to be cooled is placed in thermal contact with either hydrogen gas or a liquid coolant. The hydrogen gas or liquid coolant exchanges heat with the element to be cooled and is constantly replenished by cooler hydrogen or liquid coolant forced through the heat exchanger by a pressure differential created in the electrochemical cell.
