1. A hydrogen storage system, comprising:
a first hydrogen tank provided in a fuel cell electric vehicle;
a second hydrogen tank provided in the fuel cell electric vehicle and configured to store hydrogen independently of the first hydrogen tank;
a manifold provided in the fuel cell electric vehicle and connected to the first hydrogen tank and the second hydrogen tank;
a hydrogen supply line configured to connect the manifold and a fuel cell stack provided in the fuel cell electric vehicle; and
a flow rate adjusting valve including a chamber housing having an operating chamber that communicates with the first hydrogen tank and the second hydrogen tank, wherein the valve is configured to:
actuate within the chamber housing in response to a difference in pressure between the first hydrogen tank and the second hydrogen tank; and
adjust a flow rate of the hydrogen to be supplied to the manifold from the first hydrogen tank and the second hydrogen tank;
wherein, when a pressure in the first hydrogen tank becomes a first pressure and a pressure in the second hydrogen tank becomes a second pressure lower than the first pressure, a flow rate of the hydrogen to be supplied from the first hydrogen tank to the manifold is increased and a flow rate of the hydrogen to be supplied from the second hydrogen tank to the manifold is decreased.
