Abstract
A fuel cell system and a method for checking for hydrogen leakage are provided. The fuel cell system includes a fuel cell module having at least one fuel cell. The fuel cell system further includes a valve coupled to the fuel cell module and a hydrogen source for allowing hydrogen to be passed to the fuel cell module or blocking hydrogen from being passed to the fuel cell module. The fuel cell system further includes a controller board coupled to the valve and the fuel cell module for checking output voltage of the at least one fuel cell to determine whether there is hydrogen leak. The control board controls the valve for blocking hydrogen from being passed to the fuel cell module when the control board determines that there is a hydrogen leak.
