Nowadays, the proton exchange membrane electrolyzer (PEMEL) is a promising and attractive technology when coupling with renewable energy sources (RES). Indeed, PEMEL can respond quickly to dynamic operations of RES. Given that must be supplied low DC voltage, DC-DC converters are mandatory. In this work, stacked interleaved buck converter used. paper, tuning proportional, integral derivative (P...

Low-temperature water electrolysis using an anion conductive polymer electrolyte has several potential advantages over other technologies, however, the fabrication of durable alkaline electrodes remains a challenge. Detachment catalysts results in loss electrochemical surface area. Simple mixtures ionomer and catalyst can suffer from poor adhesion because only physical is used to bind component...

Through a variety of material screening experiments, Al was selected as the added metal and constituted a multiple micro-electrolysis system of Fe/C/Al. The metal proportion of alloy-structured filler was also analyzed with the best Fe/C/Al ratio of 3:1:1. The regular Fe/C/Al multiple micro-electrolysis fillers were prepared using a high-temperature anaerobic roasting method. The optimum condit...

Identification of low cost, highly active, durable completely noble metal-free electro-catalyst for oxygen reduction reaction (ORR) in proton exchange membrane (PEM) fuel cells, oxygen evolution reaction (OER) in PEM based water electrolysis and metal air batteries remains one of the major unfulfilled scientific and technological challenges of PEM based acid mediated electro-catalysts. In contr...

Widespread use of hydrogen energy is contingent on the development reliable and economical sources hydrogen. Electrolysis from renewably-derived low-carbon electricity a potentially viable method generation. Prime among electrolysis technologies are those utilizing ion-conducting polymers (ionomers) including proton-exchange-membrane water electrolyzer (PEMWE). However, these need to exhibit in...

Renewable energy storage and conversion is nowadays a major target for the scientific community. Their into hydrogen clear clean alternative their storage. This work shows, first time, results of SO2 depolarized electrolysis production at high temperature (120–170 °C) using phosphoric acid doped polybenzimidazole (PBI) membranes. A standard thermally cure PBI membrane with were used manufacturi...

This study investigated the effects of the electrolytic treatment in the simulated wastewater with aromatic amine nphenyl-n-isopropyl-p-phenylenediamine (Flexzone 3P) using Ti/TiRuO2 electrodes under 0.025 A/cm 2 (DC) for different electrolysis durations (5; 15; 30; 45 and 60 min). Conductivity, pH, UV-visible spectra, gas chromatograms, toxicity and biodegradation tests were carried out. Durin...

This study explores the hypothesis that Magnetic Resonance Imaging (MRI) can image the process of electrolysis by detecting pH fronts. The study has relevance to real time control of cell ablation with electrolysis. To investigate the hypothesis we compare the following MR imaging sequences: T1 weighted, T2 weighted and Proton Density (PD), with optical images acquired using pH-sensitive dyes e...
