Abstract

The invention provides a fuel cell system and a power supply method using the same. The fuel cell system comprises a humidification cell unit, a power supply cell unit and an auxiliary cell unit. The humidification cell unit comprises a first cathode outlet and a first anode outlet. The power supply cell unit comprises a second cathode inlet, a second anode inlet, a second cathode outlet and a second anode outlet. The first anode outlet is connected to the second anode inlet. The first cathode outlet is connected to the second cathode inlet. The auxiliary cell unit comprises a third anode inlet and a third cathode inlet. The third cathode inlet is connected to the second cathode outlet. The third anode inlet is connected to the second anode outlet. The fuel cell system improves power supply cell unit generating efficiency, effectively utilizes reaction gas, prevents resource waste and reduces a fuel cell system cost.

Description

technical field [0001] The present application relates to the field of fuel cell technology, in particular, to a fuel cell system and a method for using it for power supply. Background technique [0002] A fuel cell is an environmentally friendly, high-efficiency, long-life power generation device. Taking the proton exchange membrane fuel cell (PEMFC) as an example, the fuel gas enters from the anode side, the hydrogen atoms lose electrons at the anode and become protons, the protons pass through the proton exchange membrane to the cathode, and the electrons also reach the cathode through the external circuit, at the cathode protons , electrons and oxygen combine to form water. The fuel cell converts chemical energy into electrical energy in a non-combustion manner, and its direct power generation efficiency can be as high as 45% because it is not limited by the Carnot cycle. As a power generation device with the battery stack as the core, the fuel cell system integrates p...
