A water draining structure for gas reaction plate of a fuel cell stack includes a gas inlet, a gas outlet, a plurality of wide gas channels parallelly arranged to communicate with the gas inlet, and a plurality of narrow gas channel parallelly arranged to communicate with the gas outlet, all provided on the gas reaction plate. Each of the wide gas channels is communicable with a corresponding one of the narrow gas channels. When an amount of reacting gas is guided into the gas reaction plate, it encounters a significant change in cross-section area from the wide gas channels to the narrow gas channels. A substantial pressure difference between the wide and narrow gas channels is generated, providing a force to blow off moisture in the wide and narrow gas channels.
