ELECTROCHEMICAL APPARATUS AND PROCESS

摘要

The electrical performance of an electrochemical apparatus such as a fuel cell and the durability of the fuel cell elements can be significantly enhanced and extended by the addition of an element between at least one electrode (the oxygen electrode and/or the fuel electrode) and the electrolyte. Performance can be additionally enhanced by the design of at least one electrode to alter its flow characteristics. An integrated separator element can additionally function as at least one electrode of the fuel cell. The electrochemical apparatus is tolerant of the utilization of sulfur bearing fuels.
