This work presents a new electrolysis-based microelectromechanical systems (MEMS) diaphragm actuator. Electrolysis is a technique for converting electrical energy to pneumatic energy. Theoretically electrolysis can achieve a strain of 136 000% and is capable of generating a pressure above 200 MPa. Electrolysis actuators require modest electrical power and produce minimal heat. Due to the large ...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

Abstract Direct catalyst coating of membranes is an obvious membrane‐electrode assembly (MEA) fabrication approach. Nevertheless, it bears significant challenges related to excessive swelling the wetted and layers during coating. Thermal decaling, which currently used in proton exchange electrolysis, cannot be with typical hydrocarbon‐based anion‐exchange due lack a glass transition point. In t...

Tap water is one of the causative factors of hospital infections. We examined the disinfective potential of electrolysis and mechanism of disinfection, and clarified the disinfective effect of electrolysis on tap water contaminated with bacteria, and discussed its clinical applications. Tap waters artificially contaminated with Pseudomonas aeruginosa, Escherichia coli, Legionella pneumophila, a...

Three different power-to-methane process chains with grid injection in two scales (1 MW el and 6 ) were analysed regarding their investment operation cost. The based on biological or catalytic bubbling fluidised bed methanation combination proton exchange membrane solid oxide electrolyser cells. A bottom-up techno-economic analysis showed a cost benefit of around 17–19% lower biomethane product...

These experiments were designed to give the dynamic electrolysis conditions of fluidized beds by the use of small palladium particles. Both direct current electrolysis and pulse power electrolysis methods were used in this study. The excess power observed was 90 mW for direct current electrolysis in D2O + 0.1 M LiOD (I=0.300 to 0.400 A). For pulse electrolysis (pulse width 1.0 μs, pulse frequen...

Water electrolysis is one of the simplest methods used for hydrogen production. It has the advantage of being able to produce hydrogen using only renewable energy. To expand the use of water electrolysis, it is mandatory to reduce energy consumption, cost, and maintenance of current electrolyzers, and, on the other hand, to increase their efficiency, durability, and safety. In this study, moder...

Pairing the electrocatalytic hydrogenation (ECH) reaction with different anodic reactions holds great promise for producing value-added chemicals driven by renewable energy sources. Replacing sluggish water oxidation a bio-based upgrading can reduce overall cost and allows simultaneous generation of high-value products at both electrodes. Herein, we developed membrane-electrode assembly (MEA)-b...

While hydrogen generation by alkaline water electrolysis is a well-established, mature technology and currently the lowest capital cost electrolyser option; polymer electrolyte membrane electrolysers (PEMWEs) have made major advances in terms of cost, efficiency, durability, installed capacity growing rapidly. This makes promising candidate for large-scale production, especially energy storage ...
