Hydrogen energy storage proton exchange membrane

What is a proton exchange membrane based electrocatalytic system?

Proton exchange membrane (PEM)-based electrocatalytic systems represent a promising technology for hydrogen production, which is equipped to combine efficiently with intermittent electricity from renewable energy sources.

What is proton exchange membrane (PEM) technology?

Owing to low maintenance costs and favorable environmental properties, the use of proton exchange membrane (PEM) technology, has attracted more attention in recent years. By using this method, the hydrogen storage concept is summarized in three main steps including production, storage, and consumption.

What is a proton exchange membrane fuel cell?

Among several types of fuel cells, proton exchange membrane fuel cells (PEMFCs) have been most successful and have already been commercialized in residential and automobile (fuel cell vehicles, FCVs) applications, owing to their high power density and efficiency at low operating temperatures (typically ca. 60–80 °C).

What is a green hydrogen energy storage concept?

Why is proton exchange membrane technology important?

It also has a high calorific value compared to petroleum products and if combined with fuel cells, it will not emit pollutant gases . Owing to low maintenance costs and favorable environmental properties, the use of proton exchange membrane (PEM) technology, has attracted more attention in recent years.

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.
