A simulation tool called HYDRA to optimize individual hydrogen infrastructure layouts is presented. The different electrolyzer technologies, namely proton exchange membrane electrolysis, anion alkaline and solid oxide as well storage possibilities are described in more detail evaluated. To illustrate the application opportunities of HYDRA, three project examples discussed. include central decen...

Water electrolysis is a thermodynamically energy-intensive process. One approach employed to make water kinetically favorable replacing the oxygen evolution reaction (OER) at anode by facile electrooxidation of biomass-feedstocks such as ethanol, methanol, glycerol, and lignin due presence readily oxidizable functional groups. In this work, we report simplistic for hydrogen generation electroly...

Currently, spray coating has attracted interest in the mass production of anode catalyst layers for proton exchange membrane water electrolysis (PEMWE). The solvent ink is a critical factor dispersion ink, microstructure layer, and PEMWE performance. Herein, various pure organic solvents were examined as substitute conventional isopropanol-deionized (IPA-DIW) mixture solvent. Among polar that e...

Ionic polymer-metal composites (IPMCs) consist of a perfluorinated ionomer membrane (usually Nafion or Flemion) plated on both faces with a noble metal such as gold or platinum and neutralized with a certain amount of counterions that balance the electrical charge of anions covalently fixed to the membrane backbone. IPMCs are electroactive materials that can be used as actuators and sensors. Th...

Ovomucoid (OMC) is the most prominent allergen causing hen's egg allergy, containing disulfide (S-S) bonds that may be responsible for its allergic action. As S-S bonds may be reduced during electrolysis, this study was undertaken to evaluate modulation of the allergic action of OMC after electrolysis. Electrolysis was carried out for 1% OMC containing 1% sodium chloride for 30 minutes with a v...

By the use of Cr-39 particle track detectors immersed in the electrolyte, we confirm that a nuclear reaction of as-yet unknown nature can take place during electrolysis. With Li2SO4 dissolved in D2O or H2O and either Pd or Ni as cathodes, a very large statistical difference in nuclear track generation is found between detector chips immersed during electrolysis and the control chips immersed in...

Coupled electro-thermal field exists widely in chemical batteries and electrolysis industry. In this study, a three-dimensional numerical model, which is based on the finite-element software ANSYS, has been built to simulate the electro-thermal field in a magnesium electrolysis cell. The adjustment of the relative position of the anode and cathode can change the energy consumption of the magnes...

The behaviors of reduction of NpO2 by controlled potential electrolysis were studied, and a unique time course of electrolysis current was observed. It was concluded that NpO2 was reduced by two reduction processes, which were the chemical reaction with Np and the electrocatalytic reduction by adsorbed hydrogen atom on platinum electrode surface. The time courses of current for controlled poten...

Numerous tracks of charged nuclear particles, emitted during electrolysis, were discovered by Oriani and Fisher (1). More recently, emission of such particles after electrolysis was discovered by Oriani (2). This presentation is based on ten experiments conducted to replicate the reported results. Seven clusters of tracks were found in two out of six electrolysis experiments. Three clusters wer...

Solid oxide fuel cells (SOFCs) can be operated in a reversed mode as electrolyzer cells for electrolysis of H2O and CO2. In this paper, a 2D thermal model is developed to study the heat/mass transfer and chemical/electrochemical reactions in a solid oxide electrolyzer cell (SOEC) for H2O/CO2 co-electrolysis. The model is based on 3 sub-models: a computational fluid dynamics (CFD) model describi...
