Abstract: An apparatus and a method for detecting malfunction in a hydrogen tank for a fuel cell vehicle system are provided to ensure reliability in driving a fuel cell vehicle by figuring out which hydrogen fuel tank does not supply hydrogen fuel through comparison between the total amount of hydrogen consumption and the amount of hydrogen supplied from each hydrogen tank. An apparatus for detecting malfunction in a hydrogen tank for a fuel cell vehicle system comprises at least one hydrogen tank(10), a plurality of temperature sensors(12), a pressure sensor(20), a fuel cell stack(26), an FPS(Fuel Processing System,24), and a control unit(30). The hydrogen tank stores hydrogen to be supplied to the fuel cell stack. The temperature sensors measure temperatures in each hydrogen tank. The pressure sensor measures pressure in the hydrogen tank. The fuel cell stack causes reaction between hydrogen and oxygen to generate electricity. The FPS supplies hydrogen to the fuel cell stack. The control unit calculates an amount of hydrogen supplied from each tank by subtracting the amount of hydrogen left in each tank obtained by using temperature and pressure in each tank after a certain time period from the initial amount of hydrogen obtained by using initial temperature and pressure, calculates a total amount of hydrogen by accumulating current generated in the fuel cell stack, calculates an amount of hydrogen periodically discharged to the outside, and compares the total amount of hydrogen consumption with the amount of hydrogen supplied from each tank for discriminating which hydrogen tank is malfunctioning and alarming the result.
