Abstract:
Provided are a reinforced composite membrane and a method of manufacturing the reinforced composite membrane, and more particularly, a reinforced composite membrane including a porous support layer; and an electrolyte membrane layer formed on one surface or each of both surfaces of the porous support layer, at least a portion of the porous support layer being impregnated with an electrolyte, and a method of manufacturing the reinforced composite membrane. The reinforced composite membrane may enhance an interfacial adhesive force between a support and the electrolyte membrane layer, and may be manufactured on a continuous mass production.
Abstract:
Provided is an apparatus for soft-sensing a fuel cell system. The apparatus includes: a connecting unit detachable from a control unit for being connected to an outside of a stationary fuel cell system; a collecting unit connected to the connecting unit and receiving data of the stationary fuel cell system; a quality variable predicting unit connected to the collecting unit and predicting a quality variable of the stationary fuel cell system based on the received data; and a monitoring unit connected to the quality variable predicting unit and outputting the predicted quality variable. The quality variable predicting unit is configured to predict the quality variable predictable including at least any one of a concentration of carbon monoxide in a reformed gas at a rear end of a fuel converting system, and a concentration of methane in the reformed gas at the rear end of the fuel converting system.

Abstract:
To provide a reactor to improve evenness in the thickness of shell metals coated on the surface of core particles by increasing area sizes in the reactor chamber to control electric potentials, the present invention is configured to comprise a top surface able to move up and down while serving as a working electrode, a wall serving as a working electrode, a bottom surface, a standard electrode, a power supplying part and a solution injecting part, wherein the top surface can move up and down automatically by an electric motor or manually. Also, the top surface is configured to be suitable for the interior diameter of the reactor chamber, for solutions inside the reactor chamber not to leak from the top surface or from the crevice between the top surface and the wall of the reactor chamber. The bottom surface of the reactor chamber may comprise an impeller or an ultrasonic wave diffuser to bring about even diffusion in the reactor chamber.
