System For Measuring Amount Of Consumed Hydrogen

Abstract: Provided is a measurement system with which it is possible to precisely derive the amount of consumed hydrogen in a fuel cell without modifying a vehicle, etc., even when there is a possibility that leaked hydrogen is included in exhaust gas from the fuel cell or from a hydrogen engine. Provided is a system for measuring the amount of consumed hydrogen in a body under test, which is a moving body that is provided with a hydrogen reactor for chemically reacting hydrogen and that uses energy obtained through the chemical reaction, or which is a component of the moving body, the system for measuring the amount of consumed hydrogen comprising: an oxygen concentration sensor that measures the concentration of oxygen included in exhaust gas from the body under test; an oxidation catalyst disposed between the hydrogen reactor and the oxygen concentration sensor, the oxidation catalyst oxidizing hydrogen contained in the exhaust gas by using oxygen included in the exhaust gas; and a hydrogen consumption amount calculation unit that calculates the amount of consumed hydrogen on the basis of the oxygen concentration measured by the oxygen concentration sensor.
