A fuel cell apparatus includes a fuel cell module, a pump, a mixing tank, a circulating piping, a valve, a cartridge, and a pressing element. The circulating piping having a first opening is connected to the fuel cell module, pump, and mixing tank. The valve is disposed at the first opening for optionally covering it. The mixing tank stores first fuel. The cartridge connected to a sidewall of the first opening stores second fuel. The concentration of the second fuel is higher than that of the first fuel. The pressing element presses the cartridge to deform it. When the pump is turned on, the valve is closed to cover the first opening, and the first fuel is transported to the fuel cell module. When the pump is turned off, the valve is opened to expose the first opening, and the second fuel is transported to the mixing tank.
