Grease Filter

4」Grease Filter

Celmet™ has been adopted in restaurants and commercial facilities.

Advantages of applying Celmet™
Collection performance
  • Compared to baffle filter, Celmet™ has higher collection performance due to its large surface area.

  • The material (nickel) can be repeatedly used by alkaline washing.

Strength and safety
  • Compared to metal fiber or ceramic, Celmet™ has less chipping and mechanical degradation, improving safety.

  • Compared to stainless steel baffle filter, Celmet™ has better fireproof performance due to lower thermal conductivity.

Weight saving
  • The weight is one-third of baffle filter.

Electrodes of Alkali Water Electrolysis

5」Electrodes of Alkali Water Electrolysis

Celmet™ has been considered as industrial hydrogen generator.

  • Advantages of applying Celmet™
  • Voltage reduction of alkaline water electrode cell

    Celmet™ is metal foam so that a zero-gap structure is possible and can reduce resistance of solution.

  • Improvement of hydrogen generation efficiency

    Compared to lath or mesh, applying Celmet™ to hydrogen electrode can increase the amount of hydrogen without increasing the cell voltage due to its large surface area.


6」Fuel Cells (SOFC)

Celmet™ has been adopted as current collector and gas flow path of industrial and institutional fuel cells.

Advantages of applying Celmet™
Low cost stack
  • No need for complex gas flow.

Compact stack
  • Celmet™ can make interconnector thinner so that Celmet™ functions as gas flow path and gas diffusion.

Reduction of pressure loss
  • High porosity can reduce pressure loss.

Improvement of the fuel availability
  • Celmet™ can improve the fuel availability because fuel gas flows uniformly.

Improvement of current collection performance of air electrode
  • Ni alloy Celmet™ can be applied as air electrode, because it has good oxidation resistance.

Fuel Cells (PEFC)

7」Fuel Cells (PEFC)

Celmet™ has been adopted as current collector and gas flow path of fuel cells for lift trucks

Advantages of applying Celmet™
Low cost
  • No need for GDL and separators with complex gas flow path, and lower pressure loss.

  • Celmet™ functions as gas flow path, gas diffusion and current collector.

Performance improvement
  • Lower resistance and high-strength compared to carbon paper.

Higher energy output
  • Higher current collection performance and improved flooding resistance – drainage is improved by capillary of Celmet™.
