Abstract

The invention provides a fuel cell system with controller, including a fuel cell reactor, a fuel supply part, an air supply part, an electric energy output part and a control part; the controller connected with the control part includes: a flow detecting component, a CO detecting component, a power detecting component, a voltage detecting component and a display part; and its control method includes the stages as follows: system-driving stage; signal-detecting stage; comparing stage; judging stage;. It beneficial effects: the controller can excellently regulate the output of electric energy according to load change; therefore it can avoid unnecessary fuel waste and simultaneously can also prevent the use inconvenience caused by electric energy insufficient.

Description

technical field [0001] The present invention relates to a fuel cell, in particular to a control device and a control method for the fuel cell system. Background technique [0002] Most of the energy used by humans is obtained from fossil fuels. However, the use of fossil fuels will cause air pollution, acid rain, and the global greenhouse effect, which will have a bad impact on the environment, and the energy efficiency is also low. [0003] In order to solve the above-mentioned problems caused by the use of fossil fuels, fuel cell systems are therefore being developed. [0004] A fuel cell system is different from a normal battery (secondary battery) in that it generates electricity by supplying fuel (hydrogen or hydrocarbon) to the cathode and oxygen to the anode. It can also be called a power generation device. [0005] The fuel of the above-mentioned fuel cell does not undergo combustion (oxidation) reaction, but undergoes electrochemical reaction by hydrogen and oxyge...
