Abstract
The present invention discloses a hydrogen supply apparatus and a method for operating the apparatus, which can protect a fuel cell and extend the service life of a fuel cell. The hydrogen supply apparatus includes a large-capacity hydrogen storage apparatus, a small-capacity hydrogen storage apparatus, a second shut-off valve, and a pressure reducing valve, etc. The small-capacity hydrogen storage apparatus is automatically filled with fuel gas when the fuel cell is operating, and when the fuel cell is in standby mode, fuel gas is transferred into the fuel cell by controlling the opening and closing time and the period of the second shut-off valve, so that protection of the fuel cell and extension of the fuel cell life are realized.
