Chemical Stability

Corrosion Resistance: In hydrogen production electrolyzers, there are electrolyte solutions such as acids and alkalis. The MHPD 2.0 PPS raw material must possess excellent corrosion resistance, being able to withstand the erosion of the electrolytes. It ensures that no chemical reactions occur during long-term use, which could lead to a decline in performance or damage to the material, thus maintaining the structural integrity and stability of the electrolyzer.

Oxidation Resistance: During the electrolysis process, redox reactions occur on the surface of the electrodes, generating substances with oxidizing properties. The MHPD 2.0 PPS raw material needs to have good oxidation resistance to prevent being oxidized, which may affect its physical and chemical properties, and avoid problems such as aging and embrittlement, thereby extending the service life of the electrolyzer.

Thermal Stability

High-temperature Tolerance: Hydrogen production electrolyzers generate a certain amount of heat during operation, especially under high current density, and the temperature may rise. The MHPD 2.0 PPS raw material should be able to maintain stable performance at relatively high operating temperatures, without deformation, decomposition or degradation, ensuring that the electrolyzer can operate normally under different working conditions.

Thermal Conductivity: Good thermal conductivity helps to quickly dissipate the heat generated inside the electrolyzer, avoiding local overheating, thus improving the electrolysis efficiency and the stability of the system. The MHPD 2.0 PPS raw material should have an appropriate thermal conductivity to achieve effective heat transfer and heat dissipation.

Mechanical Properties

High Strength: The electrolyzer is subjected to various mechanical forces during assembly and operation, such as pressure and tension. The MHPD 2.0 PPS has sufficient strength, including tensile strength and bending strength, etc., to withstand these external forces, preventing problems such as cracking and deformation, and ensuring the tightness and structural reliability of the electrolyzer.

High Toughness: To avoid brittle fracture when subjected to impact or vibration, the MHPD 2.0 PPS raw material should have good toughness, be able to absorb a certain amount of energy, improve the impact resistance and fatigue resistance of the material, and enhance the overall stability and durability of the electrolyzer.

Dimensional Stability: Under different temperature and humidity conditions, the MHPD 2.0 PPS raw material should have good dimensional stability, ensuring that all components of the electrolyzer can maintain precise dimensions and shapes, guaranteeing the fitting accuracy between components, and preventing problems such as poor sealing or a decline in electrolysis efficiency caused by dimensional changes.

Electrical Properties

Insulation: The MHPD 2.0 PPS raw material needs to have good insulation properties to prevent current leakage inside the electrolyzer, avoid safety issues such as short circuits, and at the same time ensure the normal progress of the electrolysis process, improving the electrolysis efficiency and energy utilization rate.

Ion Conductivity: In some electrolyzer designs, the PPS material may be required to have a certain degree of ion conductivity to facilitate the transfer of ions between the electrolyte and the electrodes, promoting the occurrence of the electrolysis reaction. This requires that the MHPD 2.0 PPS raw material can have an appropriate ion conductivity while meeting the insulation requirements.
