Precious metal catalysts Noble metal platinum-based catalysts Noble metal platinum-based catalysts (PGMs) are the best performing HER catalysts available. It has low overpotential, high exchange current density and remarkable reaction stability. It can effectively reduce the hydrolysis energy barrier and increase the reaction rate. The disadvantage is that resources are scarce and expensive, which limits...Read More
What is membrane electrode assemblies? The membrane electrode assemblies(MEA) is the most central component of the hydrogen fuel cell. And is the core site for several material transport and electrochemical reactions. Its preparation technology not only directly affects the performance of the battery. But also is crucial to reduce the cost of the battery and...Read More
Hydrogen production by water electrolysis Hydrogen production by water electrolysis is the dissociation of water molecules under the action of direct current to produce oxygen and hydrogen, which are precipitated from the anode and cathode of the electrolyzer respectively. Depending on the electrolyzer diaphragm material, hydrogen production by water electrolysis is usually divided into alkaline...Read More
A new joint report by the International Renewable Energy Agency (IRENA) and the European Patent Office (EPO) shows that innovations in electrolysis technology are accelerating the reduction in the cost of renewable hydrogen production. Why we need to accelerate the innovation of electrolysis technology? As more and more countries pursue deep decarbonization strategies, hydrogen produced...Read More
South Korean researchers have discovered a material to produce hydrogen more cheaply. It is in a water electrolysis process and costs much less than the standard material platinum. What is the new catalyst for hydrogen production? The scientists “carbonized” a fabric-like material by subjecting it to temperatures in excess of 900 degrees Celsius, making the...Read More
What is PEM electrolyzer? (1) The PEM water electrolyzer adopts proton exchange membrane to isolate the gas on both sides of the electrode, avoiding the disadvantage that the gas of alkaline electrolytic hydrogen production diaphragm is easy to penetrate. (2) The equipment mainly contains PEM electrolyzer and BOP. What is PEMWE? The PEM water electrolyzer...Read More
According to foreign media reports: Recently, Germany, Belgium, and the Netherlands. Denmark committed to building at least 150 GW of installed offshore wind power capacity in the North Sea by 2050, to build a “green power plant” for Europe. But the task is challenging because the European wind power supply chain is unprofitable. And the...Read More
