Technology
CryoStruct™
Created through a unique powder metallurgy process and freeze-casting technology, CryoStruct™ offers a broad selection of metals and alloys that can be shaped into precise forms – all while utilizing significantly less polymer. This metal foam outperforms alternatives by providing high porosity (up to 85%), small pore sizes (down to 5 micrometers), high surface area (up to 9 times more), and high uniformity of pore distribution.
PyroStruct™
Using a patented space holder technique, PyroStruct™ foams range in pore sizes from 100 micrometers to 2 millimeters, maintaining foam porosity while enhancing surface area. Its shape flexibility and capacity to cover a wide range of pore sizes allow PyroStruct™ to push the boundaries of innovative applications for metal foams.
Applications
- Hydrogen fuel cells and Electrolyzers: Our foams enhance efficiency and durability in PEMFCs and both PEM and AEM electrolyzers. They function as gas diffusion and porous transport layers, reducing ohmic and contact resistance, increasing corrosion resistance, and improving catalyst usage rates.
- Batteries: In Lithium-ion batteries, our foams serve as current collectors to maximize charge/discharge speed and suppress dendrite growth. Metal foams also function as anodes or cathodes in Ni-MH and Zinc-ion batteries, enhancing surface area to boost reaction areas.
- Structural components: Function as a lightweight shock-absorbent material with excellent vibration dampening and high flexural rigidity.
- Thermal applications: Serve as efficient heat sinks, the porous structure provides a higher heat exchange area and so enhances heat dissipation efficiency. In vapor chambers, metal foams facilitate fluid flow through efficient capillary action, improving heat absorption and evaporation rates.
