Exergetic efficiency of a PEM electrolyser at various operating temperatures and pressures
This paper presents a comprehensive exergy analysis on a large scale 12,900kW PEM electrolyser at various operating temperatures and pressures. Calculations of physical exergy, mass flow rates and exergetic efficiency are performed at temperatures (T/To) and pressures (P/Po) ranging from 1 to 1.4 and 1 to 10, respectively. The results showed that at 1 atm (P/Po=1), the exergetic efficiency of an ...

A comparative evaluation of palladium and platinum nanoparticles as catalysts in proton exchange membrane electrochemical cells
The goal of the present study is the development and comparative characterisation of carbon-supported and nanostructured Pd- and Pt-based electrocatalysts for hydrogen oxidation in Proton Exchange Membrane (PEM) H2/O2(air) fuel cells and proton reduction in PEM water electrolysers. Catalysts have been synthesised in a solution using a combined impregnation/reduction polyol method. They have been ...

Cheaper Solution to Producing Hydrogen by Continuous Splitting of Water
For the first time, scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have demonstrated that an inexpensive catalyst can split water and produce hydrogen gas continuously for hours in the extreme environment of a commercial device. Stanford graduate student McKenzie Hubert with equipment used to test a cheap alternative to an expensive ...
