A fuel cell system includes a fuel cell stack, a fuel inlet conduit, a water inlet conduit, and a hydrometer, such as an alcoholometer. The hydrometer is adapted to provide a measurement of a water-to-fuel ratio of a fuel inlet stream within the fuel inlet conduit. The water inlet conduit is adapted to provide a quantity of water to the fuel inlet conduit in order to achieve a desired water-to-ratio being provided to the fuel cell stack.
