There is provided a hydrogen consumption quantity measurement system that, even in a case in which there is a possibility that leakage hydrogen is contained in exhaust gas from a fuel cell or a hydrogen engine, makes it possible to accurately determine a total quantity of hydrogen consumption of the fuel cell without having to modify a vehicle or the like. This hydrogen consumption quantity measurement system measures a hydrogen consumption quantity in a test body, which is formed by a moving body or portion thereof that includes a hydrogen reactor that causes hydrogen to undergo a chemical reaction, and that utilizes energy obtained from this chemical reaction, and includes an oxygen concentration sensor that measures a concentration of oxygen contained in exhaust gas from the test body.
A hydrogen consumption quantity measurement system that measures a hydrogen consumption quantity in a test body, which is formed by a moving body or portion thereof that includes a hydrogen reactor that causes hydrogen to undergo a chemical reaction, and that utilizes energy obtained from this chemical reaction, comprising:

A hydrogen consumption quantity measurement method in which a hydrogen consumption quantity is measured in a test body, which is formed by a moving body or portion thereof that includes a hydrogen reactor that causes hydrogen to undergo a chemical reaction, and that utilizes energy obtained from this chemical reaction, and which is characterized in that,
A hydrogen leakage quantity measurement method in which an oxygen concentration in exhaust gas after hydrogen contained in the exhaust gas discharged from a test body, which is formed by a moving body or portion thereof that includes a hydrogen reactor that causes hydrogen to undergo a chemical reaction, and that utilizes energy obtained from this chemical reaction, has been made to pass through an oxidation catalyst that performs oxidation using oxygen contained in the exhaust gas, and an oxygen concentration in the exhaust gas that has not been made to pass through the oxidation catalyst are measured, and a quantity of hydrogen leakage from the hydrogen reactor is measured by comparing these oxygen concentrations.
