Modified aluminium-magnesium alloy fuel cell

Abstract

This invention relates to a modified Al, Mg alloy fuel cell, the metal anode of the fuel cell is a modified AlMg alloy anode, the cathode is an air electrode composed of an anode catalyst electrode, a water-proof permeability film and conduction Cu silk screen plated with Ag, the anode catalyst electrode is a film made of a mixture of active carbon, MnO2, graphite and SiO, the water-proof permeability film is one made of the mixture of Teflon, emulsion agent, a changed material of ethane black and carbon, and the anode catalyst electrode, the water-proof permeability film and the Cu silk screen are suppressed and sintered to form the air electrodes, the electrolyte is a neutral one containing salt, said metal anode is set at the center of a sealed shell, the two air electrodes are set at both sides of the metal anode and the shell is charged with electrolyte.

Description

【Technical field】 [0001] The invention relates to a fuel cell, in particular to a high-efficiency modified aluminum and magnesium alloy fuel cell. 【Background technique】 [0002] A fuel cell is a new type of battery that directly converts chemical energy into electrical energy and heat energy. It differs from conventional batteries in that as long as there is fuel and oxidant supply, there will be continuous power output. Due to its advantages of high energy conversion efficiency, no pollution, quick start, long battery life, high specific power, and high specific energy, it has broad applications in fixed power generation systems, on-site power supplies, distributed power supplies, space vehicle power supplies and vehicle power supplies. For example, fuel cells have become the research and development focus of major automobile manufacturers in the world, and have made great progress. With the rapid development of electronics and communication technology, digital products s...

Problems solved by technology

However, if other metals are used as catalytic electrodes, the voltage, efficiency and output power of the battery will be lost by about 40%.

The catalytic object of hydrogen-oxygen fuel cell is hydrogen (H 2 ), and there are certain safety hazards in the use, transportation and storage of hydrogen fuel, and the catalytic electrode is expensive in terms of materials and use

Another type of zinc-air fuel cell uses zinc alloy as the anode and potassium hydroxide (KOH) as the electrolyte, which will cause serious environmental pollution when used.

[0003] Due to the existence of the above problems, the practical application of fuel cells is limited
