The process of hydroelectric hydrogen production consists of the following main steps:
Electrolysis of water: in an electrolyser, water (H₂O) is broken down into hydrogen (H₂) and oxygen (O₂). This process usually involves two electrodes: an anode and a cathode.
Applied Voltage: A DC voltage is applied between the two electrodes in the electrolyser by a power supply. This voltage causes water molecules to react at the anode and cathode.
The reaction process:
At the anode: water molecules lose electrons (are oxidised) to produce oxygen and hydrogen ions (H⁺).
At the cathode: hydrogen ions gain electrons (are reduced), producing hydrogen gas.
Gas collection: the hydrogen and oxygen produced are collected separately from the electrolyser. Usually, hydrogen is produced at the cathode and oxygen at the anode.
Separation and purification: The collected gases may require further separation and purification to ensure that the purity of the hydrogen meets the requirements of the application.
Storage and Use: The purified hydrogen can be stored or used directly in fuel cells, industrial production or other applications.
The efficiency and safety of this process is influenced by a variety of factors such as electrolyser design, catalyst material, operating conditions, and more.
Titanium Fiber Felt for PEM is mainly used as a Gas Diffusion Layer (GDL) in water electrolysis hydrogen production. Its uses include:
Gas Transport: The porous structure of Titanium Fiber Felt for PEM allows hydrogen and oxygen to diffuse efficiently in the electrolyzer, ensuring that the reactants reach the electrode surface quickly, thus improving reaction efficiency.
Enhanced Electrolysis Performance: The excellent electrical conductivity and corrosion resistance of Titanium Fiber Felt for PEM improves current density and hydrogen production during electrolysis, reducing energy consumption.
Improved Stability: Titanium Fiber Felt for PEM performs well in high-temperature and corrosive environments, improving the overall stability and life of the electrolyser.
Mechanical Support: Titanium Fiber Felt for PEM provides mechanical support for the electrolyzer, maintaining the structural integrity of the electrodes and preventing deformation due to gas generation.
Overall, Titanium Fiber Felt for PEM plays an important role in the electrolysis of water for hydrogen production, directly affecting the efficiency and quality of hydrogen production.
