Hydrogen station and hydrogen filling method for pressure accumulator in hydrogen station

摘要

The present invention prevents excessive increase in pressure accumulator temperature as a result of filling hydrogen in to the pressure accumulator, in a hydrogen station. The hydrogen station (1A) increases the pressure of hydrogen from a hydrogen storage vessel (60) (hydrogen supply source), by using a compressor (2), fills same in to the pressure accumulator (31), and supplies hydrogen inside the pressure accumulator (31) to a hydrogen fuel tank such as a vehicle-mounted tank in a fuel cell vehicle (FCV), via a dispenser (4). In this hydrogen station (1A), hydrogen filling of the pressure accumulator (31) when the hydrogen temperature inside the pressure accumulator (31), the temperature of the pressure accumulator (31), or the outside air temperature around the pressure accumulator (31) is at least a prescribed temperature is controlled so as to suppress hydrogen increases or pressure increases inside the pressure accumulator (31), in comparison to when the temperatures are less than the prescribed temperature.
