Hydrogen (H2) production is pivotal in the global shift towards a net-zero carbon economy. Its elemental abundance and zero-emission combustion position it as an ideal renewable energy source. However, the journey to harness hydrogen’s full potential is fraught with challenges, particularly in storage and transportation. Researching viable hydrogen carriers is critical, as conventional ...
As the world intensifies its focus on green hydrogen production, a critical factor that often goes unnoticed is water treatment. The process of producing hydrogen through electrolysis involves complex chemical reactions and precise atomic calculations, making water treatment an essential part of the equation. In this article, we will discuss how understanding the atomic composition of water can ...

The gas purifier was confirmed to be capable of removing the residual NH3 for a proton exchange membrane fuel cell (PEMFC). The fuel cell, when powered by the cracked and purified gas mixture, revealed comparable performance and power output as compared with the pre-mixed fuel gas mixture (75%H2/25%N2), demonstrating the feasibility of the whole ...
What are Fuel Cells? Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a battery, and a dynamic equilibrium is maintained. ...
Abstract In the present work, carbon nanotubes (CNT) and CNT-carbon nanohorns (CNH) (0, 30, 50, 70 and 100 wt.% CNH) composite Buckypapers (BPs) were fabricated using vacuum filtration technique. Structure and property relation of composite BPs were studied using scanning electron microscope, four probe technique, BET surface area and contact angle measurements. Properties such as electrical ...

Sulfonated Poly(ether ether ketone) (SPEEK) and its composites are explored as potential alternatives for Nafion in fuel cell applications. In this work, we investigate the effects of the silica functionalisation route on the thermal, mechanical and structural properties of SPEEK-Silica composite membranes. We compare two different methods – direct sulfonation and ...

The chlor-alkali industry, one of the largest chemical industries in India and growing at an annual rate of 3.3%, is expected to grow along with the growing Indian economy. This MW size proton-exchange membrane (PEM) fuel cell product captures hydrogen produced in the chlor-alkali industry to create on site electricity and provide plant operators ...
This paper presents the thermodynamic modelling of a proton exchange membrane (PEM) fuel cell at various operating conditions through energy and exergy analyses. ...
Fuel cells are widely recognised as a technology of the future and as a potential replacement for the internal combustion engine in cars and other vehicles.This article looks at the potential for fuel cells to provide auxiliary power to vehicles, rather than primary motive power. Today, hydrogen-fuelled proton exchange membrane (PEM) ...
In London, Brent crude also rose $1.24 (3.4%) to $37.75 a barrel on the International Petroleum Exchange. But some of the questions we have for hybrid technology are now dependability in cold weather starting, reliability in highway driving standards, added to these ever so alluring fuel cost savings. ...
