Water recycling system for fuel cell

A water recycling system for fuel cell in which a condenser is connected to a fuel cell module for recycling moisture generated by the fuel cell module in operation, comprising:

• a water trough, receiving condensed water from the condenser and connecting with a first throttle valve;
• a first pump, being connected to the first throttle valve and sucking moisture passing through the first throttle valve;
• a fuel tank, having fuel inside, being connected to a second throttle valve, and the second throttle valve being connected to the first pump for the fuel being capable of being pumped out via the first pump;
• a mixing tank, being connected to the first pump for receiving mixing liquid of water and the fuel from the first pump;
• and
• a second pump, being connected to the mixing tank for pumping the mixing liquid to the fuel cell module and supplying the fuel with proper thickness to the fuel cell module;
• wherein, a thickness sensor and a level sensor are arranged in the mixing tank to detect thickness of the fuel and liquid level of the mixing liquid in the mixing tank;
• the first throttle valve, the first pump, the second throttle valve, the second pump, the thickness sensor and the level sensor are electrically connected to a micro control unit (MCU) and the MCU is capable of receiving and reading out data of fuel thickness detected by the thickness sensor and data of liquid level detected by the level sensor so as to control actuation of the first throttle valve, the first pump, the second throttle valve and the second pump for regulating and control the thickness of the fuel in the fuel tank.
