Autonomous power supply based on fuel cells and alumohydrogen generator

---

Scheme of autonomous power source

Area of application

Brief description

The autonomous power source will consist of fuel cells and a hydrogen generator, in which hydrogen will be formed as a result of aluminum hydrolysis of energy-storing substances (ESSs). Samples of low-temperature hydrogen-air fuel cells (HAFCs) and their batteries will be created based on high-performance, next-generation membrane-electrode blocks. ESSs capable of evolving hydrogen from water at room temperature will also be developed, and a hydrogen generator design will be proposed.

Expected results

It is assumed that the use of promising developments in the creation of an autonomous power source will increase the ratio of electricity generated to the mass of its source. Modern autonomous current sources based on fuel cells and hydrogen generators will have different performance and provide electrical power to a wide range of electrical and electronic devices.

Advantages

Combining an alumohydrogen generator and fuel cells in one unit will provide an autonomous power source for portable and mobile electric apparatuses and devices, which is especially important in the absence of stationary power supply. Generation of electric current in the developed power sources is an environmentally friendly process that does not worsen the environment.

Competitor

Project development

A methodology for the preparation of aluminum based ESSs has been developed, in particular, with the use of low-melting metals and alloys as activating additives. It has been shown that such ESSs are capable of evolving hydrogen from water without additional heating. The authors are experienced in the development of experimental samples of hydrogen-air and hydrogen-oxygen fuel cells using efficient nanodispersed electrocatalysts with low platinum content based on carbon nanotubes and nanodispersed carbon black.
