Title:
HYDROGEN SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2022189556
Kind Code:
A
Abstract:
To maintain the pressure of hydrogen gas in a fuel cell at a target pressure and suppress the reduction in the life of a pressure reducing valve in a hydrogen supply device for supplying hydrogen gas from a hydrogen tank to a fuel cell through the pressure reducing valve and a hydrogen supply portion.SOLUTION: When the pressure P1 of hydrogen gas inside a fuel cell FC becomes equal to or lower than predetermined pressure Pth1 which is lower than target pressure Pt, an injector INJ is operated to supply the hydrogen gas to the fuel cell FC, and when the pressure P1 of the hydrogen gas inside the fuel cell FC becomes equal to or higher than the target pressure Pt, the injector INJ is stopped to stop the supply of hydrogen to the fuel cell FC, and when the hydrogen gas pressure P1 in the fuel cell FC is higher than the predetermined pressure Pth1 and lower than the target pressure Pt, the injector INJ is alternately activated and stopped.SELECTED DRAWING: Figure 1
