Problems solved by technology

[0026] However, in the existing fuel cell stack, the fuel electrode 12 is formed as a single body. If there are two or more different types of reactive substances inside the fuel cell stack 10, the effects of the two substances cannot be effectively exerted due to the incompatibility of their electrode characteristics. performance

Embodiment Construction

[0042] The fuel cell hybrid electrode structure of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0043] As shown in FIG. 5, according to the fuel cell stack of the present invention, an electrolyte membrane 110 is placed in the middle, and a fuel electrode 120 and an air electrode 130 are arranged. However, the fuel electrode 120 is composed of at least a plurality of electrode parts 121 and 122 made of two or more different substances.

[0044] Electrolyte membrane 110 is to transmit H + As the membrane made of polymer material, for example, a polymer ion-exchange membrane that has electrical conductivity in a wet state is used.

[0045] Among them, the fuel electrode 120 is composed of a plurality of first electrode parts 121 and second electrode parts 122 that separate the support body and the catalyst layer. The first electrode part 121 is for the BH in the aqueous solution state ...

Abstract

The present invention discloses a hybrid electrode structure of fuel cell, and it is charcterized by that the electrolyte membrane is placed in the middle, the fuel pole and air pole are laminated, and when the fuel and air which can be supplied to the fuel pole and outside of air pole are passed through fuel pole and air pole, the water and electricity can be produced, and the electrode portion can be divided into more than two electrode portions by means of fuel pole, and every electrode portion can be laminated by using different substances, so that the hydrogen gas produced in reaction on first electrode portion can be reutilized on the second electrode portion. Said reutilization process can raise the performance of fuel cell pile and can raise utilization rate of the fuel.

Description

technical field [0001] The present invention relates to fuel cells, especially with B compounds (BH 4 ) is an invention in the aspect of fuel cell hybrid electrode structure that can improve fuel utilization efficiency in a fuel cell system where fuel is used. Background technique [0002] Most of the energy humans use is derived from fossil fuels. However, the use of these fossil fuels has caused problems such as air pollution, acid rain, and global warming, which have a very bad impact on the environment. Moreover, fossil fuels themselves have problems such as low energy efficiency. [0003] Fuel cells are proposed to solve the problems of fossil fuels. It is different from a general battery (secondary battery). A fuel cell provides fuel (hydrogen or hydrocarbons) to the cathode from the outside, oxygen to the anode, and performs an electrochemical reaction through the reverse reaction of electrolysis of water to generate electricity and Thermal battery system. Its ess...
