Core Characteristics of Open-Cell Foam Carbon

Three-dimensional interconnected through-pores (controllable PPI ranging from 10 to 100), ultra-high porosity (up to 97%), electrical conductivity, acid and alkali corrosion resistance, high temperature resistance; fluids can freely flow through the skeletal framework.

Electrochemical Industry (Largest Mature Commercial Market)

① Three-dimensional porous electrodes for flow batteries (vanadium / iron-chromium / zinc-bromine flow energy storage)

Compared with carbon felt, it resists compression and maintains stable flow channels with evenly distributed electrolyte, serving as the mainstream upgraded electrode material for large-scale energy storage power stations.

② Porous transport layers and electrode substrates for water electrolysis hydrogen production (PEM / alkaline electrolyzers)

Provides diffusion pathways for gas and liquid, and supports catalyst loading; resistant to strong acids and alkalis.

③ Electrodes for electrocatalytic wastewater treatment, heavy metal electrodeposition recovery, and electrochemical sensors

④ Three-dimensional conductive frameworks for supercapacitors and sodium-ion batteries

Hydrogen Energy Equipment

① Gas filtration and hydrogen purification components

High-temperature impurity filtration and oil-water separation for hydrogen.

② Flame arrestor and flameless venting buffer substrate (cutting-edge application)

The interconnected open-cell carbon skeleton quenches flames and dissipates shockwaves. Advantages over aluminum foam: superior high-temperature resistance, anti-oxidation performance, flame retardancy without melting, suitable for venting devices of hydrogen and combustible gases.

Comparison Note: Aluminum foam delivers excellent energy absorption at room temperature but oxidizes and softens above 500°C; open-cell foam carbon can withstand temperatures exceeding 2000°C in an inert atmosphere.

③ Gas diffusion carriers for fuel cells and supporting skeletons for SOFC solid oxide fuel cells

High-Temperature Filtration & Catalysis Industry

① Monolithic catalyst carriers for high-temperature corrosive flue gas

VOC catalytic combustion and denitrification; open pore channels offer low air resistance and high catalyst loading capacity.

② Filtration of molten metals, molten salts, and high-temperature industrial chemical fluids

③ Industrial oil-water separation and adsorption of organic pollutants

Aerospace & National Defense Military Industry

① High-temperature thermal insulation, thermal protection and ablative substrates

Thermal insulation components for aircraft and wind tunnel tooling.

② Sandwich core materials for wave-absorbing stealth materials

The porous structure can be compounded with wave-absorbing agents to fabricate radar absorbing panels.

③ Energy-absorbing materials for explosion shock buffering and explosion-proof interlayers

④ Lightweight sandwich panel core materials (alternative to aluminum honeycomb for high-temperature operating conditions)

Thermal Management (Distinguish Material Grades for Selection)

① Thermal runaway flame-retardant insulation layers for power battery packs (Class A non-combustible, no toxic flue gas at high temperatures)

② Composite skeletons for phase-change heat dissipation (impregnated with paraffin PCM, used for temperature control of high-power power supplies and lasers)

Acoustic Noise Reduction

High-temperature sound-absorbing materials for high-temperature power equipment, industrial furnaces and aero-engine compartments. Ordinary polyurethane foam can only be used at room temperature, while open-cell foam carbon enables long-term high-temperature noise absorption.

Biomedicine & Laboratory Applications

① Porous scaffolds for bone repair (biologically inert, controllable pores induce cell growth)

② Standard electrolytic reaction electrodes for laboratories

Other Niche Application Scenarios

① Porous supports for vacuum equipment and substrates for plasma discharge

② Lightweight tooling for high-temperature metallurgical furnaces
