The hydrogen evolution reaction (HER) is one of the most promising methods obtaining high-purity hydrogen. However, high cost and limited resources materials with low cathodic overvoltage values, such as platinum group metals, are main obstacles to use HER for on an industrial scale. Therefore, it necessary develop new alternative their production. One catalysts based refractory in particular t...
Previous studies have shown that electrolytic lesions of the dorsal hippocampus render the instrumental performance of rats insensitive to selective degradation of the action-outcome contingency (Corbit and Balleine, 2000). In the present experiments, we sought to replicate this finding and to examine the effects of excitotoxic lesions. In the first three experiments, rats with either electroly...
Hydrogen refueling stations (HRSs) are critical for the popularity of hydrogen vehicles (fuel cell electric vehicles—FCEVs). However, due to high installation investment and operating costs, proliferation HRSs is difficult. This paper studies with on-site electrolytic production storage devices proposes an optimization method minimize total costs including both (OPT-ISL method). Moreover, acqui...
The authors studied the influence of volume fraction and morphology δ-ferrite on hydrogen embrittlement austenitic stainless steel 08Kh19N9T obtained by electron beam additive manufacturing. It is experimentally shown that in additively-manufactured samples, long lamellae form a dense “net” interphase boundaries (austenite/δ-ferrite, δ-phase 20 %) contribute to accumulation. Also, being “easy” ...
The development of methods and apparatus for magnetic measurements capable of an accuracy of i per cent makes it necessary to consider factors which have heretofore been considered negligible. One of these factors, the temperature coefficient of magnetic permeability, is the subject of the present paper. Many workers have studied the effects of temperature on the magnetic permeability of iron a...
Abstract The utilization of water electrolysis hydrogen in DC power grids can effectively improve the absorption and renewable energy, production supply is a key equipment. This article designs an isolated supply, which adopts bidirectional active H-bridge topology modular design. In process production, use constant current voltage control, development control strategies for but input ripple el...
Indonesia has an ocean area of 5.8 million km2, water is the event decomposition compounds (H2O) into hydrogen gas (H2) and oxygen (O2) by using electric current through water. In this study, electrolysis at electrolytic concentration containing NaCl can take place quickly with various catalysts NaOH, H2SO4 concentrations 0.1M, 0.25M, 0.5M, 0.75M, currents 15A, 25A 35A. From results it was fo...
In response to electricity markets with growing levels of wind energy production and varying electricity prices, this research examines incentives for investments in integrated renewable energy power systems. A strategy for using optimization methods for a power system consisting of wind turbines, electrolyzers, and hydrogen fuel cells is explored. This research reveals the investment potential...
The electrostatic attraction between electrons and nuclei is a fundamental force in electrochemistry. This drives the interaction nuclei, providing potential for redox reactions. As result, it basis of chemistry. In recent years, organic electrochemistry has made significant progress oxidative hydrogen evolution coupling sacrificial anode electroreduction, thanks to its efficient environmentall...
The paper presents a method of hydrogen sampling from an electrolysis cell for further analysis the composition generated gas. Solving problem sampling, system "electrolytic - separator gas pipette filled with distilled water" was used. ensures supply produced in to without mixing atmospheric gases. Sampling (oxygen) directly electrolyzer carried out evacuating storage tanks and connecting pipe...
