Abstract: Systems and methods are provided for pumping hydrogen within an electrochemical cell system. In one example, a liquid driven hydrogen pump includes an impeller positioned within a flow path of a gas, and a turbine coupled to the impeller by a shaft and positioned within a flow path of a liquid. A flow of the liquid is driven by a liquid pump based on operation of the electrochemical cell system and the flow of the liquid across the turbine drives rotation of the impeller and an increase in a flow of the gas.
