Problems solved by technology

But because this kind of fuel cell changes the output of the system according to the size of the load, in order to correspond to the maximum output, the air pump 33 runs at the maximum capacity all the time, so not only will there be power loss and the so-called 'overflow' caused by excessive humidification. flow' phenomenon, but also has the problem of lower fuel cell performance

Abstract

Humidification quantity controller composed of humidity detecting element, temperature adjustment unit and control unit is setup inside fuel cell system including fuel cell pile, fuel supplying unit, air supplying unit and electric energy output unit. When load is changed, the humidification quantity controller adjusts relative humidity of air by using heater / cooler or air pump so as to increase or decrease damping quantity at air poles on fuel cell pile. Thus, air pump is operated under suitable output, preventing loss of electric energy. The invention avoids issues of performance deterioration of fuel cell etc. caused by superabundant humid or shortage of humid.

Description

technical field [0001] The invention relates to a system for generating electric energy by using a fuel cell, in particular to a fuel cell humidification adjustment device capable of adjusting the humidification amount of an air electrode in a boron fuel cell system using liquid fuel such as boron compounds. Background technique [0002] Most of the energy used by humans is obtained from fossil fuels. The use of these fuels will not only cause serious environmental problems such as air pollution, acid rain or the global warming effect, but also have low energy utilization efficiency. Fuel cells can be used instead of the above-mentioned fossil fuels. Unlike ordinary batteries, a fuel cell is a battery system that generates electricity and heat using an oxidation reaction of fuel (hydrogen or hydrocarbon fuel) supplied externally to the anode and a reduction reaction of oxygen supplied to the cathode. It can also be regarded as a power generating device. The fuel cell powe...
