Abstract
A hydrogen filling system to fill a hydrogen fuel tank with hydrogen includes a high-pressure water electrolysis device capable of electrolyzing water to produce oxygen and the hydrogen. A hydrogen pipe connects the high-pressure water electrolysis device and a filling mechanism to fill the hydrogen fuel tank with the hydrogen. At least one hydrogen storage tank is provided to the hydrogen pipe to store the hydrogen produced by the high-pressure water electrolysis device at substantially a same pressure as a maximum filling pressure of the hydrogen fuel tank. A first valve mechanism is arranged downstream of the at least one hydrogen storage tank. A bypass pipe is provided to the hydrogen pipe and connects the high-pressure water electrolysis device and the filling mechanism to bypass the at least one hydrogen storage tank and the first valve mechanism. A second valve mechanism is arranged on the bypass pipe.
