It operates based on the principle of generating an electrical current through a chemical reaction between oxygen and a fuel, typically a metal like lead or zinc. The current produced is directly proportional to the amount of oxygen present, making EGFCs crucial for ensuring safe breathing gas mixtures in underwater environments. This entry delves into the fundamental principles, historical development, technical specifications, applications in scuba diving, maintenance practices, and regulatory considerations of electro galvanic fuel cells."}
