Abstract
This tank device comprises a fuel gas tank that stores fuel gas to be supplied to a gas consuming device, a first pressure sensor that detects the gas pressure when the fuel gas tank is filled with gas, a second pressure sensor that detects the pressure of the fuel gas supplied from the fuel gas tank to the gas consuming device, and a sensor output evaluation unit. The sensor output evaluation unit determines the gas pressure differential between the gas pressure detected by the first pressure sensor when the fuel gas tanks is filled with gas and the gas pressure detected by the second pressure sensor when the fuel gas is first supplied from the fuel gas tank to the gas consuming device after the gas filling, makes a judgment that there is not an output abnormality is any of the first and second pressure sensors if the gas pressure differential is within a given threshold value, and makes a judgement that there is an output abnormality in either of the first and second pressure sensors if the gas pressure differential is beyond the given threshold value.
