Samples of palladium sheet supplied by IMRA Japan were tested for anomalous energy production using electrolysis in heavy water and a sensitive calorimeter. Several samples were found to produce significant power above that being applied to produce electrolysis. This behavior was found to correlate with certain properties of the palladium metal. In addition, the anomalous heat was shown to orig...

This study deals with the preparation and characterisation of catalyst-coated membranes for an alkaline water electrolysis process. For this purpose, a chloromethylated anion-selective block copolymer styrene-ethylene-butylene-styrene 1,4-diazabicyclo[2.2.2]octane functional groups was used both as polymer electrolyte membrane ionomer binder. Non-PGM catalysts (platinum group metals), specifica...

The effect of the addition three oxophilic co-metals (Sn, Mo and Re) on electrochemical performance Pd in ethanol oxidation reaction (EOR) was investigated by performing half-cell membrane-less electrolysis cell experiments. While additions Sn Re were found to improve significantly EOR Pd, produced no significant promotional effect. When added amounts (50:50 ratio), a 3–4 fold increase mass-nor...

Polymer electrolyte membrane (PEM) electrolyzer or alkaline is required to produce green hydrogen using renewable energy such as wind and/or solar power. PEM and differ in many ways, instantly basic materials, system configuration, operation characteristics are different. Building an optimal water hydrolysis by closely grasping the of each type great help building a safe ecosystem well efficien...

A bottleneck for the deployment of Anion Exchange Membrane Water Electrolysis (AEMWE) is manufacturing efficient and long lasting anodes cathodes cells. Highly performant bimetallic Ni/Fe catalyst films with various atomic ratios have been prepared by magnetron sputtering in an oblique angle configuration (MS-OAD) used as AEMWE. Electrocatalytic experiments a small three-electrode cell thorough...

Electrolysis is seen as a promising route for the production of hydrogen from water, part move to wider “hydrogen economy”. The electro-oxidation renewable feedstocks offers an alternative anode couple (high-overpotential) electrochemical oxygen evolution reaction developing low-voltage electrolysers. Meanwhile, exploration new membrane materials also important in order try and reduce capital c...
