Applications of Foam Metal in Sound Absorption and Noise Reduction When sound waves enter porous foam metal, they cause the medium within the voids (typically air) to undergo periodic vibrations. Friction between the air and the pore walls dissipates sound energy, converting it into heat. Furthermore, the framework of porous foam metal possesses excellent thermal conductivity, enabling rapid energy dissipation. Furthermore, the unique pore structure of porous foam metal induces phenomena such as sound wave reflection, refraction, and interference, which also contribute to its sound-absorbing properties.

Modified Sponge (Conductive Sponge): Polyurethane foam materials offer excellent sound insulation and absorption properties, along with corrosion resistance and waterproofing. High-quality polyurethane materials incorporate flame-retardant designs and exhibit superior sound absorption capabilities.

Soundproofing and noise-reducing materials used in automobiles should meet the following criteria as much as possible:

The material should be lightweight. Lightweighting is a major trend in the entire automotive manufacturing field. After installation, lightweight materials should not significantly increase the vehicle's curb weight, thereby avoiding increased fuel consumption. The material should exhibit good sound insulation and sound absorption performance across a wide frequency range, with long-term stable and reliable performance. Possess adequate strength to resist damage during installation and use, exhibit low susceptibility to aging, demonstrate excellent weather resistance, and offer a long service life. Maintain a clean appearance without causing contamination. Be moisture-proof, water-resistant, corrosion-resistant, and resistant to mold and decay. Exhibit low flammability, ideally with fire-retardant properties. Be environmentally friendly, free from harmful substances such as asbestos, glass fiber, and heavy metals like lead. Be easy to work with, such as being readily cut and providing strong adhesion.

Hydrogen energy finds extensive applications across transportation, steelmaking, chemical processing, power generation, and heating sectors. Hydrogen production serves as the foundation for all hydrogen energy utilization pathways, with water electrolysis being the most critical method for establishing an electro-hydrogen energy structure and enabling large-scale conversion and utilization of new energy sources. Nations worldwide recognize clean hydrogen as a vital pathway for clean energy transition and achieving carbon neutrality.

Currently, hydrogen is primarily categorized into three types based on production methods and carbon emissions: gray hydrogen, blue hydrogen, and green hydrogen:

① Hydrogen produced from fossil fuels (including coal, natural gas, etc.) or as a byproduct of industrial processes. This is the most technically mature production route currently available, but it generates carbon emissions during production, hence the hydrogen produced is termed “gray hydrogen”;

② “Blue hydrogen” is produced by applying carbon capture technology during gray hydrogen production. This method effectively reduces carbon emissions during hydrogen production but does not entirely eliminate them;

③ “Green hydrogen” is produced through water electrolysis. This method generates no carbon emissions, but the technology for producing green hydrogen is currently less mature than fossil fuel-based methods, resulting in higher costs.

HGP hydrogen production electrode materials utilize conductive sponge as the substrate. Through processes including electrodeposition of metallic nickel, high-temperature oxidation, and hydrogen-protected reduction, high-performance ammonia-making electrode materials are produced. The products exhibit excellent strength, initial performance, and corrosion resistance. They can be fabricated into electrode plates tailored to hydrogen generator dimensions for practical applications, with various thicknesses available.
