In alkaline hydrogen production electrolyzers, the membrane is the core component second only to the electrodes, serving two main functions: first, to strictly block hydrogen and oxygen gases, eliminating the risk of mixing and explosion; and second, to act as a hydroxyl ion conduction channel, ensu...
I. Overview of Alkaline Water Electrolysis for Hydrogen Production Systems
Alkaline water electrolysis (ALK) refers to the technology of producing hydrogen by electrolyzing water in an alkaline electrolyte environment. The electrolyte is typically a 30% (w/w) potassium hydroxide (KOH) solution. The...
In the fabrication of membrane electrode assemblies (MEAs) for hydrogen fuel cells, the quality of the catalyst slurry plays a decisive role in the MEA's performance . Many engineers have had the painful experience of having perfect material parameters on the formulation sheet, but the prepared slur...
The European Committee for Standardization (CEN) recently released a draft standard, FprEN 62282-3-400:2026, for stationary fuel cell power generation systems. This standard sets specifications for the entire lifecycle of small-scale stationary fuel cell power generation systems and will inject new...
Against the backdrop of accelerated global energy structure transformation, the costs of renewable energy sources such as photovoltaics and wind power continue to decline. As water electrolysis hydrogen production technology matures, the cost of green hydrogen is rapidly approaching that of traditio...
Hydrogen fuel cells, with their high efficiency and cleanliness, have garnered widespread attention in fields such as drones and commercial vehicles. Hydrogen energy education in vocational schools transcends disciplinary boundaries, requiring both theoretical integration and practical support. Ther...
In recent years, investment in the green methanol sector has continued to surge, with planned and under-construction projects reaching 51 million tons by the end of last year. However, amidst this boom, very few projects have actually been implemented and are operating smoothly . Due to multiple fac...
Hydrogen, as a pollution-free, renewable, and clean energy source, and with its high energy density, is becoming a core development direction in the energy transition process. Hydrogen production by water electrolysis is the mainstream technology for green hydrogen production, and the technol...
“Generate hydrogen using solar energy, then produce electricity when needed—freeing yourself from the grid and achieving zero-carbon independence.” This vision sounds appealing. As a technical team with years of experience in the energy sector, we must caution residential users wit...
As a core technology in the field of clean energy conversion, hydrogen fuel cells consistently demonstrate near-perfect performance potential in laboratory environments—high efficiency, high power density, excellent start-up characteristics, and stability—making them a "technology star"...
In fuel cell technology, the choice of cooling system not only affects heat dissipation efficiency but also directly determines the core lifespan of the stack. Behind the two mainstream cooling approaches—air cooling and liquid cooling—lie “genetic-level” differences that imp...
Amid the global wave of energy transition, fuel cells are regarded as a core component of future energy systems due to their high efficiency and clean characteristics. However, progressing from the laboratory to industrial application, the improvement of their power generation efficiency has consist...
