    Abstract: Disclosed is a carbon fiber web including polymer nanofibers. Specifically, the carbon fiber web includes: a dispersed structure of carbon fibers; and polymer nanofibers distributed among and bonding the constituent carbon fibers of the dispersed structure. The carbon fiber web exhibits excellent characteristics in terms of flexural strength, gas permeability and electrical properties while possessing a tensile strength sufficient to undergo continuous processes for mass production. Also disclosed are a gas diffusion medium using the carbon fiber web, a gas diffusion layer including the gas diffusion medium, a membrane electrode assembly including the gas diffusion layer, and a fuel cell including the membrane electrode assembly. The use of the carbon fiber web ensures high performance of the membrane electrode assembly and the fuel cell.

    Abstract: Disclosed herein is stack-type flow energy storage system. More particularly, the system includes a stack-type electrode cell composed of fluidic electrode material mixed with an electrolyte and storage tank for the electrode material, thereby remarkably improving stability, output and energy density. The stack-type flow energy storage system is advantageous in that unit cells, each consisting of a cathode, a separation membrane and an anode, are connected in parallel or in series to each other to make a stack cell, thus remarkably increasing output power. Further, the stack-type flow energy storage system is advantageous in that the sizes of slurry storage tanks connected to an electrode cell are adjusted, thus determining the required specification of energy density.
