PEM hydrogen production selects the perfluorosulfonic acid proton exchange membrane. It has good chemical stability, proton conductivity, and gas separation. As a solid electrolyte to replace asbestos membrane, it can effectively block electron transfer and improve electrolyzer safety. The main components of PEM water electrolyzer are proton exchange membrane, cathode catalytic layer, cathode gas diffusion
According to Salzgitter Mannesmann Forschung, the electrolyzer broke through to produce 200Nm³ of green hydrogen for titanium felt per hour for the first time, and the project was able to demonstrate 84% power efficiency (LHV, net thermal efficiency). This is an unprecedented high efficiency. In contrast, electrolysis techniques such as alkaline or PEM (proton exchange
Hydrogen production of titaniumn felt Currently, the main hydrogen production method is coal-to-hydrogen. But it is unsustainable and has high abatement costs. So it is suitable for large-scale hydrogen production of titanium felt. Besides, the potential of hydrogen production of titaniumn felt from electrolytic water is high. But the price of electricity is a problem
According to foreign media reports: Seoul will develop green hydrogen production technology to produce gas fuel from sewage sludge generated by water recycling centers. Gasification sludge can be used to produce green hydrogen. While his is a hydrogen titanium felt preparation technology that does not use any fossil fuel in the manufacturing process. A water
As we’ll know, carbon taxes were once the key to the growth of demand for clean hydrogen energy. But in the long run, due to the low cost of carbon taxes and free quotas, its influence has weakened. Instead, countries and companies have set net-zero emissions targets, which will be a stronger driver of hydrogen
The PEM water electrolyzer uses PEM to conduct protons, isolates the gas on both sides of the electrode. And it avoids the shortcomings associated with AWE’s use of strong alkaline liquid electrolytes. The PEM water electrolyzer uses PEM as the electrolyte and pure water as the reactant. In addition, the hydrogen permeability of PEM is
1950年代後半に、電気化学チタン繊維固体電解質としてイオン伝導性ポリマーを使用するというアイデアが生まれました。当時、この技術は高分子電解質膜やプロトン交換膜（PEM）としてではなく、固体高分子電解質（SPE）として知られていました。PEM電解質の開発は、過フッ素化イオン交換膜であるナフィオンの発見と密接に関連していました。 DuPontによって発見され、最初のPEM電解質は1960年代にGeneralElectricによって開発されました。 PEM電解槽は、主に2つの電極とプロトン交換膜で構成されています。拡散層材料については、現在、業界では焼結フェルト、チタンフェルト、カーボンフェルトが主な材料ルートとして使用されている。中でもチタンフェルトは陽極に、カーボンフェルトは陰極に主に使用されています。拡散層充填材は、材料と自社工程とのベストマッチングを実現するため、基本的にカスタマイズが要求され、各社の工程レベルを反映する核心的な側面の一つにもなっている。 General Clad は、長年、金属焼結マットの分野で活躍し、その後、プロセスの類似性の原則のもと、水素エネルギー用途のチタン繊維マットに事業を拡張した会社です。その結果、現在ではチタン繊維マットの研究開発、生産、販売を統合した近代的な国家的ハイテク企業となり、多くの知的財産権と強い国際総合競争力を持っています。
(1) Demand for hydrogen energy The European Clean Hydrogen Alliance believes that the role of hydrogen energy in the energy transition process mainly includes: realizing large-scale and efficient consumption of renewable energy. Redistributing energy between different industries and regions, and acting as an energy buffer carrier to improve the energy system. Resilience, reduce carbon emissions
Proton exchange membrane electrolyzer (PEM) hydrogen production cost analysis Alkaline electrolyzer has low electrolytic efficiency, requires the use of strong caustic alkali, requires the removal of water and alkali from the hydrogen. That is difficult to start and change the load quickly, and cannot adjust the speed of hydrogen production quickly. So it is poorly
On March 10, the Australian and German governments jointly launched the HyGATE program, a hydrogen innovation and technology incubation program. It aims to promote cooperation between Australia and Germany to set up a hydrogen energy value chain between the two countries. Then they will find pilot, test and demonstration projects along the hydrogen supply chain.
