Magaluma fuel cell power supply unit

Abstract

A magaluma fuel cell power supply unit is characterized in that the unit consists of a fuel cell stack (20) formed by connection of more than one monomer modified magaluma fuel cells (10) and a control circuit (30). More than one monomer modified magaluma fuel cells (10) combine the fuel cell stack (20) through series connection, parallel connection or series and parallel connection. The monomer modified magaluma fuel cells (10) are jointed with each other by locking or splicing through a concaveconvex structure. The magaluma fuel cell power supply unit can run independently, continues supplying power for a longer time, is convenient in application and simple in maintenance, can supply power normally in the regions without electricity and in the power down mode and is combined by a plurality of magaluma fuel cells.

Description

【Technical field】 [0001] The invention relates to a power supply device capable of providing direct current or alternating current, in particular to an aluminum-magnesium alloy fuel cell power supply device formed by combining a plurality of high-efficiency modified aluminum and magnesium alloy fuel cells. 【Background technique】 [0002] As we all know, electricity is one of the main energy sources in people's lives, and electricity is available to people in two ways: alternating current and direct current. 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 s...

AI Technical Summary

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] For this reason, the applicant has provided a kind of "modified aluminum, magnesium alloy fuel cell" in the patent application that the application number is 200710073300.2, and it has solved the existing problem of traditional fuel cell effectively, but this application does not solve its The problem of practical application, that is, it does not solve the problem of how to form a single modified aluminum and magnesium alloy fuel cell into an industrialized fuel cell device
