FUEL CELL SYSTEM AND HUMIDIFICATION DEVICE OF THE SAME

摘要

PURPOSE: A fuel cell system is provided to improve moisturizing performance by a gas-gas moisturizing method and to improve stack performance and durability. CONSTITUTION: A fuel cell system(100) comprises a stack(10) which consists of electricity-generating assembly of a unit fuel cell(17); an air supply unit(30) for supplying air to the air electrode(13) of the fuel cell; and a moisturizing apparatus(200) which conducts a membrane moisturization of supply air supplied through the air supply unit and exhausts air at high temperature; a hydrogen supply unit(70) for supplying hydrogen to a fuel electrode of the fuel battery; and a hydrogen supply pipe(75) which supplies hydrogen to a fuel electrode(15) through the moisturizing apparatus.
