This article aims to demonstrate the process of building a low-cost water electrolyzer using common materials and to analyze the influence of practical experiments on students' knowledge. Practical classroom experiments ...

Hydrogen obtained from water electrolysis in addition to being sustainable becomes commercially competitive when a high degree of purity is sought. Ideally such purity is achieved by keeping the electrolyzer on a constant ...

Conventional alkaline electrolyzers used for water splitting can considerably increase their efficiency upon modification of the surface of the electrode. Here we present in operando evidence of activation of a conventional ...

The renewed concern for the care of the environment has led to lower emissions of greenhouse gases without sacrificing modern comforts. Widespread proposal focuses on energy produced from renewable sources and its subsequent ...

Zero-gap liquid alkaline water electrolyzers have great potential for hydrogen production. In order to enhance their actual performance, one of the key components to investigate is the anionic exchange membrane that allows ...

This study delves into the techno-economic benefits of integrating Proton Exchange Membrane electrolyzers with photovoltaic systems for hydrogen production, with a keen focus on cost optimization strategies. A comprehensive ...

This paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen ...

Hydrogen produced from carbon free sources, or green hydrogen, has been identified as an important tool for the decarbonization of various industries. The aim of this study is, first, to understand the different methods ...

Hydrogen (H2) can be a critical factor in achieving a more sustainable society reducing carbon emissions worldwide in the long run. However, there are some challenges to be solved yet. One of these challenges is that, right ...
