20150207155 | FUEL CELL AND MANUFACTURING METHOD THEREOF HAVING INTEGRATED MEMBRANE ELECTRODE ASSEMBLY AND GAS DIFFUSION LAYER - A fuel cell having a membrane electrode assembly (MEA) comprising an electrolyte membrane, an anode and a cathode; and a gas diffusion layer (GDL) combined with both surfaces of the MEA is provided. In particular, the GDL includes a first layer having a first surface that comes in contact with a reaction region of the MEA, a second layer formed on a second surface of the first layer, and a third layer formed along a peripheral portion between a first region in which both the first layer and the second layer are formed and a second region in which only the second layer is formed. The first layer may be a first microporous layer, the third layer may be a second microporous layer having a viscosity lower than that of the first microporous layer, and the second layer is not the first microporous layer and the second microporous layer. | 07-23-2015 |
20150276579 | INTERFACIAL ADHESION STRENGTH MEASURING APPARATUS AND METHOD OF A GAS DIFFUSION LAYER FOR FUEL CELLS - An interfacial adhesion strength measuring apparatus of a gas diffusion layer for a fuel cell is provided. The apparatus includes a pair of load applying parts that are each adhered to outer surfaces of a substrate configuring the gas diffusion layer of the fuel cell and a micro porous layer coated on the substrate and is configured to apply a tension force in a direction in which the substrate and the micro porous layer are separated from each other. A first adhering part is applied to one of the load applying parts and is adhered to the substrate and a second adhering part is applied to the other of the load applying parts and is adhered to the micro porous layer. In addition, the first and second adhering parts contain materials of which contact angles with the substrate or the micro porous layer are different from each other, respectively. | 10-01-2015 |
20160126577 | PROCESS FOR SEPARATING ELECTRODE FOR MEMBRANE-ELECTRODE ASSEMBLY OF FUEL CELL AND APPARATUS THEREFOR - Disclosed are a process for separating an electrode for membrane-electrode assemblies of fuel cells from the decal transfer film and an apparatus for separating the electrode. In particular, during the electrode separating process, only an electrode is separated from the decal transfer film on which the electrode is coated, without any damage, by a freezing method for freezing the specimen on the deionized water surface, and thus, wasting the expensive MEA is prevented. Thus, mechanical properties of the pristine electrode can be rapidly quantified in advance, and therefore, long term durability evaluation period during developing MEA having excellent durability is substantially reduced. | 05-05-2016 |
