Molecular sieve manufacturer explains the application of molecular sieves in fuel cells

Molecular sieves are a type of natural and synthetic important porous materials that have important applications in industrial processes such as chemical separation and purification, chemical synthesis, fuel conversion, pollution control, and reduction. The discovery of MCM-41 material in 1992 has attracted many researchers to study the synthesis and application of macroporous molecular sieves and ordered mesoporous materials. Compared to typical molecular sieves, mesoporous materials have a wider range of pore size and composition. Studies have shown that they are good catalysts, adsorbents and membrane materials. They not only have many applications in traditional chemical process, but also have potential applications in microelectronics, sensors and agriculture. Next, the editor of molecular sieve manufacturer will briefly introduce the application of molecular sieves in fuel cells.
Fuel cells can provide clean and effective energy supply for fixed, mobile, and portable devices. Molecular sieves and mesoporous materials are increasingly being used to improve the performance of fuel cells. The use of these materials can increase proton transport capacity, reduce fuel crossover, and improve water inlet and outlet control of electrolyte membranes. At the same time, molecular sieves and mesoporous materials are also used as electrodes and electrocatalytic materials in fuel cells, applied in fuel conversion, reforming, and storage.
Recent studies have also shown that using molecular sieves as electrolyte membrane materials outperforms PFSA membranes in high-temperature proton exchange membrane fuel cells. In addition, molecular sieves can improve the fuel crossover problem in direct methanol fuel cell, but there are still challenges in preparing new molecular sieves with high proton conductivity. Although low conductivity hinders the application of molecular sieves in electrocatalysts, several exciting studies have shown that molecular sieve catalysts have high efficiency in the electro oxidation of methanol and ethanol, and molecular sieve template carbon materials have achieved good results in electrocatalytic reactions.
Molecular sieves will continue to play an important role in fixed, mobile, and portable battery equipment. Although recent research on proton conducting membranes of molecular sieves has mainly focused on polymer composite membranes, it is expected that there will be more and more research on proton conducting membranes of molecular sieves. The progress made in the synthesis, assembly, and manufacturing of composite structures from molecular sieves will have a significant impact on proton conductive membrane materials, thereby affecting the development of fuel cells. The research and development of ultra-thin molecular sieve films and micro processing play an important role in the miniaturization of portable energy generation equipment. The design of molecular sieve membranes requires optimization in terms of specific surface area, strength, and portability. In the future, catalyst carriers, fuel barriers, and conductive proton membranes will be optimized and integrated to form a mixed membrane composed of different molecular sieve layers. Using this mixed membrane will assemble fuel cells with superior performance. Hunan Providence New Materials Co., Ltd is a professional molecular sieve manufacturer which can provide USY zeolite, NaY zeolite, REY zeolite, ZSM-5 zeolite, welcome to consult.
