The fuel battery mainly comprises a liquid fuel, a cathode catalyst, an electrolyte membrane and an anode catalyst, wherein the fuel of the fuel battery is a hydrazion-borane solution. The hydrazion-borane (N2H4BH3, HB) is a stable and non-poisonous molecular solid, and has the characteristics that the hydrogen content is high, the transportation is convenient, the storage is safe, and the environment-friendly and non-pollution effects are realized. The direct hydrazion-borane fuel battery has the advantages that the output voltage, energy conversion efficiency and energy density are high, the storage is easy, the safety is good, and the direct hydrazion-borane battery can be used as a portable power source of mobile equipment.

Description

technical field [0001] The present invention relates to a direct type fuel cell, more specifically, the present invention relates to a direct type hydrazine borane fuel cell. Background technique [0002] With the rapid development of the global economy, energy demand is also increasing. However, the global distribution of non-renewable energy is extremely uneven and increasingly scarce. At the same time, the impact of fossil fuel combustion on global climate change and environmental changes is also increasing. Therefore, under the dual pressure of resources and environment, it is imminent to find renewable, pollution-free, safe and efficient new energy sources. Among them, fuel cells have the advantages of wide source of raw materials, high energy conversion rate, and low pollution, so they are considered to be one of the main ways of energy supply in the future. [0003] Among various types of fuel cells, proton exchange membrane fuel cells (PEMFC) are considered to be o...

Problems solved by technology

For direct methanol fuel cells, the fuel does not have the problem of difficult storage and transportation, but the reactivity is low and the catalyst is easily poisoned, especially methanol will permeate between the cathode and anode, which will cause serious loss of battery performance

Studies on direct ethanol fuel cells have shown that there is a C-C bond in the molecular structure of ethanol, so it is completely electrooxidized to generate CO 2 Difficult, plus various by-products are often formed in the process; formic acid has low energy density as a battery fuel, and formic acid is corrosive and toxic

In addition, the oxidation of these small organic molecules will produce the greenhouse gas CO 2 , not conducive to environmental protection
