Abstract: A method is provided for producing electrodes of flow cell having high power density. A plurality of seeds are distributed on a surface of a conductive carbon material. The seeds are etched into nanoparticles to form carbon nanotube (CNT) electrodes. The present invention can be applied to vanadium redox flow cell with advantages of the CNT electrodes, such as conductivity, corrosion resistance, mechanical strength and specific and electrochemical surface area. Electrons are directly passed to the material through CNTs and then to an external electronic load for improving power density of flow cell, making a cell pack more compact and reducing energy consumption on charging and discharging without using noble metal material.

Abstract: A gas-reforming catalyst is modified to obtain stability in high temperature. The catalyst uses ?-Al2O3 as a carrier and is nano-porous. Hence, reaction surface is greatly broadened; and platinum contained inside does not become bigger after times of use. The catalyst does not deposit carbon and has long life. The stability of the catalyst can be still remained even at a temperature higher than 800° C.

Abstract: A cathode electrophoretic deposition (EPD) suspension is provided by mixing an ionomer solution with an electrolyte. An anode EPD suspension is provided via mixing carbon nanomaterial (CNM)-supported catalyst with a solution of the same composition as that of the cathode EPD suspension. Ultrasonication and high-speed stirring are executed on the cathode and anode EPD suspensions, thus turning them into homogenous suspensions. There is provided a low-voltage EPD apparatus incorporated with a porous material to separate it into anode and cathode compartments. The anode and cathode EPD suspensions are filled in the anode and cathode compartments, respectively. An inert gas is introduced into the anode compartment for stirring the anode EPD suspension. An electrode base substrate is used as the anode of the EPD apparatus. A low-voltage direct current (DC) power supply is used to supply DC low voltage to the EPD apparatus, thus evenly coating a catalyst layer on the substrate.

Abstract: The present disclosure provides a gas reaction device. Reactions are happened on a fixed bed and/or a slurry bed in four reaction states. Thus, by using the four reaction states, reactions are thoroughly completed with the same catalyst. Or, different reactions are completed with different catalysts for different purposes.
