Abstract: PURPOSE: A polymer electrolyte fuel cell system is provided to supply secondary hydrogen as fuel to a fuel cell without a reformer and to ensure the simplification and stabilization of the system by supplying the fuel and air using an eductor instead of a pump. CONSTITUTION: A polymer electrolyte fuel cell system includes: a secondary hydrogen source(100) for generating hydrogen; a fuel supply system(300) which receives the hydrogen generated in the secondary hydrogen source and supplies the hydrogen and air to a fuel cell; and the fuel cell(200) which receives the hydrogen and oxygen through the fuel supply system and produces the electricity by the reaction. The fuel cell includes a fuel electrode creating protons and electrons by receiving the hydrogen and an air electrode producing water by receiving the oxygen.
