AI Technical Summary
The large space occupied by activated carbon in existing air filters reduces the filtration area and dust holding capacity, affecting the working stability and durability of hydrogen fuel cells.
The filter cloth and activated carbon plate are combined into a structure. The filter cloth forms multiple adsorption sections and pleated sections. The activated carbon plate is embedded in the adsorption sections. The filter cloth is bent in the pleated sections. The multiple adsorption sections are arranged side by side in the thickness direction of the activated carbon plate, which enhances the compactness of the structure and the dust holding capacity.
Within a limited space, the filtration area and dust holding capacity have been increased, extending the service life of the filter element, reducing maintenance costs, and improving the working stability and durability of the hydrogen fuel cell.
