A vehicle including a relay welding diagnosis function and a relay welding diagnosis method performed in the vehicle, is configured to be connectable to a charger providing a charging voltage, and includes a fuel cell configured to provide a stack voltage, a multi-converter configured to increase the level of the charging voltage or the stack voltage and to output the charging voltage or the stack voltage having the increased level as a boosted voltage, a charging relay disposed between the charger and the multi-converter, and a battery configured to store electrical energy of the boosted voltage. The multi-converter includes a voltage booster connected between the charging relay and the battery and configured to generate the boosted voltage and a converter controller configured to diagnose whether the charging relay is welded using a result of sensing an input-terminal voltage and an output-terminal voltage of the charging relay.
