DC power supply using fuel cell |
摘要 |
A power supply system (1) includes a fuel cell (40) and a battery (20) connected in parallel. A DC-DC converter (30) is connected to the battery (20). A maximum output ratio of the fuel cell (40) and the battery (20) is set to be in a range where the output of the fuel cell (40) is within 65 to 80% of the total output. Accordingly, electric power loss owing to conversion performed by the DC-DC converter (30) is reduced to achieve a high energy efficiency. <IMAGE> |
