| Abstract(E) | For fuel cell automobiles, hydrogen refueling protocol is standardized in SAE J 2601 and JPEC-S 0003. But filling into small capacity containers of 2 kg or less has not been standardized. Since the mass flow rate of hydrogen gas to a motorcycle is much smaller than that to an automobile, the precooled supply of gas at a temperature of -40℃ rises easier. Therefore, under the JARI hydrogen refueling interface standardization WG, a new hydrogen refueling protocol to small capacity containers assuming fuel cell motorcycles called ‘MC Formula Moto’ was proposed. Refueling tests inside thermostatic chambers were carried out with this protocol, and we examined how MC Formula Moto works, including the point of safety. As a result, we confirmed the safety of MC Formula Moto. Additionally, the target subject of refueling small capacity containers has been clarified. First, start-up fueling and MATexpected can be utilized to reduce the fueling time. And reducing m1, which consists of the mass from the precooler to the B/A in a station, is effective in reducing fueling time as well. In environments under 40°C, fueling stopped in the second half of filling because controlled pressure exceeded the upper pressure tolerance due to reaching the minimum flow rate. It is considered possible to reach a higher SOC when selecting a smaller Cv value valve even in high-temperature environments. |
