20150236366 | FLEXIBLE FUEL CELL AND METHOD OF FABRICATING THEREOF - Provided is a flexible fuel cell. The flexible fuel cell includes: an anode including an anode end plate structure made of a polymer material and having a hydrogen flow channel formed therein, and a current collector having a conductive layer deposited on the structure; a cathode including a cathode end plate structure made of a polymer material and having an air flow channel formed therein, and a current collector deposited on the structure; and a membrane electrode assembly (MEA) including a polymer electrolyte membrane having a catalyst layer attached to the surface thereof, and provided with a gas diffusion layer (GDL) on at least one surface thereof, wherein the polymer material includes an adhesive polymer and a curing agent mixed at a ratio of 4:1-20:1, and the membrane electrode assembly is interposed between the anode and the cathode and subjected to compression, wherein the compression is carried out while the ends of the membrane electrode assembly, anode and cathode are bent and tensile stress is applied thereto or compressive stress is applied thereto. | 08-20-2015 |
20140212641 | PROCESS FOR PRODUCING 3-DIMENSIONAL STRUCTURE ASSEMBLED FROM NANOPARTICLES - The present invention relates to a process for producing a 3-dimensional structure assembled from nanoparticles by using a mask having a pattern of perforations, which comprises the steps of: in a grounded reactor, placing a mask having a pattern of perforations corresponding to a determined pattern at a certain distance above a substrate to be patterned, and then applying voltage to the substrate to form an electrodynamic focusing lens; and introducing charged nanoparticles into the reactor, the charged particles being guided to the substrate through the pattern of perforations so as to be selectively attached to the substrate with 3-dimensional shape. According to the process of the present invention, a 3-dimensional structure of various shapes can be produced without producing noise pattern, with high accuracy and high efficiency. | 07-31-2014 |
