The physical process occurring when liquids, gases, or suspended matter adhere to the surfaces of, or in the pores of, an adsorbent material.
Adsorption is a physical process which occurs without chemical reaction.
Air is also used to remove the water by-products from the electrochemical process that takes place. Typically, air is drawn through a filter by an electric compressor and then pressurized through an exhaust-driven turbo compressor. The site at which oxidation occurs in an electrochemical cell. The lattice of carbon atoms remains continuous around the circumference. The nanotubes are designed to be very small in order to store hydrogen.
