Abstract: A water recycling system for fuel cell includes a water trough, a first pump, a fuel tank, a mixing tank and a second pump. The water trough receives condensed water from the condenser and connects with a first throttle valve. The first pump is connected to the first throttle valve. The fuel tank is connected to a second throttle valve, and the second throttle valve is connected to the first pump. The mixing tank is connected to the first pump and the second pump respectively. 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.

Abstract: A storage device capable of detecting liquid level for liquid fuel required by a fuel cell includes a main storage tank, a measurement pipe and a liquid level detection device. The main storage tank is employed to receive the liquid fuel. The measurement pipe is independent from the main storage tank and communicates with the main storage tank via a tube section. The liquid level detection device is attached to the measurement to measure level of the liquid fuel.

Abstract: A fuel cell device includes a fuel cell main body, a balance of plant and a water collecting trough. The fuel cell main body is employed to generate power. The balance of plant is connected to the fuel cell main body. The water collecting trough is disposed under the fuel cell main body and the balance of plant for collecting flooded water of the fuel cell main body and the balance of plant. Hence, problems resulted from water flooding can be overcome effectively.

Abstract: A condenser in a fuel cell device includes a casing and a plurality of heat dissipating elements. The casing formed with an enclosed structure and provides casing walls with a steam intake port, a steam outlet port and a plurality of drain ports and a containing space is defined by the casing walls. The heat dissipating elements are disposed in the containing space above the drain ports and arranged to constitute a spiral passage. The spiral passage has an initial end is disposed at the intake port and a terminal end at the outlet port. The drain ports are positioned under the heat dissipating elements. Hence, steam generated during the fuel cell device processing electrochemical reaction can be discharged effectively.

Abstract: A fuel cell structure includes at least a cathode passage plate and a load member. The cathode passage plate is capable of transferring chemical energy to electrical power output. The load member receives the cathode passage plate and defines at least a partition for the inner sides of walls of the load member being able to space apart from the cathode passage plate.

Abstract: A structure of a circuit board interface for electrically connecting at least one fuel cell module and at least one electronic device is disclosed. The circuit board interface comprises at least one base plate having a electronic circuit disposed thereon, a first interface positioned on the base plate for electrically connecting to the electronic circuit and the fuel cell module, a second interface positioned on the base plate for electrically connecting to the electronic circuit and the electronic device.
