Energy storage hydrogen fuel cell

What is a hydrogen fuel cell?

This can be achieved by either traditional internal combustion engines, or by devices called fuel cells. In a fuel cell, hydrogen energy is converted directly into electricity with high efficiency and low power losses. Hydrogen, therefore, is an energy carrier, which is used to move, store, and deliver energy produced from other sources.

What is hydrogen storage?

Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation.

Can hydrogen be stored in a fuel cell?

Hydrogen for fuel cells is commonly stored in pressurized tanks, whereby safety and portability can be problematic. Here, a rechargeable proton exchange membrane fuel cell with an internal hydrogen storage polymer that is cyclable up to 50 times is presented.

Can hydrogen fuel cell technology save money?

A breakthrough in hydrogen fuel cell technology, achieved through collaborative research, has substantially lowered costs by replacing platinum metals with silver in catalysts, marking a significant step towards affordable and efficient green energy storage.

Can hydrogen be used for electricity storage?

During the discharge phase, the stored hydrogen is either used in fuel cell or burnt directly to produce electricity. One major drawback in using hydrogen for electricity storage is the substantial energy losses during a single cycle .

Why is hydrogen a potential energy storage medium?

Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
