Abstract: Processes for the production of metal nanoparticles. In one aspect, the invention is to a process comprising the steps of mixing a heated first solution comprising a base and/or a reducing agent (e.g., a non-polyol reducing agent), a polyol, and a polymer of vinyl pyrrolidone with a second solution comprising a metal precursor that is capable of being reduced to a metal by the polyol. In another aspect, the invention is to a process that includes the steps of heating a powder of a polymer of vinyl pyrrolidone; forming a first solution comprising the powder and a polyol; and mixing the first solution with a second solution comprising a metal precursor capable of being reduced to a metal by the polyol.

Abstract: A cell unit for a fuel cell can include an electrolyte membrane, an electrode unit that includes an anode formed on one side of the electrolyte membrane and a cathode formed on the other side of the electrolyte membrane, and a porous current collector formed by coating a conductive material onto the porous surfaces of the electrode unit. It can be possible to reduce the contact resistance between the electrodes (the anode and the cathode), and their respective current collector, to thereby increase current collection efficiency and it can also be possible to make the thickness of the end plates thinner than a conventional design without sacrificing performance, to thereby decrease the overall size of a fuel cell.

Abstract: Disclosed are a cell unit for a fuel cell and a method for manufacturing the same. The cell unit for a fuel cell can include an electrolyte membrane; an electrode unit, comprising an anode being formed on one surface of the electrolyte membrane and a cathode being formed on the other surface of the electrolyte membrane; a current collector, being stacked on the electrode unit to be electrically connected to the electrode unit; and a conductive layer, being interposed between the electrode unit and the current collector to reduce a contact resistance between the electrode unit and the current collector. With the present invention, the cell unit for a fuel cell can reduce contact resistance between the anode and the cathode and the current collector. Accordingly, it can be possible to reduce the overall size of the fuel cell by reducing the required thickness of the end plate.
