The invention provides a fuel cell hydrogen circulation system and a fuel cell vehicle. The fuel cell hydrogen circulation system comprises a gas source assembly, a gas-water separator, an exhaust assembly, a compensation module and a first controller, wherein the gas source assembly is connected with an anode inlet of a fuel cell stack, the gas-water separator is connected with a circulation pipeline, the anode outlet of the fuel cell stack is connected with a first pipeline through the circulation pipeline, the exhaust assembly is connected with the circulation pipeline, the gas source assembly and the compensation module are connected with the first controller, the compensation module is connected with the exhaust assembly and used for determining expected pressure drop in the first pipeline, and the first controller is used for controlling the pressure of hydrogen supplied to the anode inlet of the fuel cell stack by the gas source assembly according to the expected pressure drop and the hydrogen pressure required by the anode inlet. By adopting the fuel cell hydrogen circulation system provided by the invention, when the exhaust assembly exhausts, the hydrogen pressure fluctuation of the anode inlet of the fuel cell stack does not exceed the fluctuation range, and the normal work of the fuel cell stack is not influenced.
