20090169930 | FUEL CELL SEPARATOR AND FUEL CELL STACK AND REACTANT GAS CONTROL METHOD THEREOF - A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area. The flow rate of the reactant gas flowing along the passage channels is increased by two times, even when the reactant gas utilizing rate is identical as compared with the reactant gas flow in the low load operation. As a result, the moisture existing in the passage channels can be more effectively discharged and the flooding phenomenon occurring in the high load operation can be prevented. By controlling the reactant gas supply in accordance with an operation condition of the fuel cell stack without experiencing pressure loss and deterioration of the utilizing rate, the flooding phenomenon and concentration polarization phenomenon that occur in the fuel cell stack can be prevented. | 07-02-2009 |

20100321452 | HYBRID PRINTING METHOD USING MOVABLE PALLET - Disclosed is a hybrid printing method using a movable pallet. The movable pallet provides for easy attachment and detachment to enable a printing process, a digital printing process, a foiling process and a flocking process. The movable pallet can be used to apply various desired inks on the surface of fabric products and the like. A printing process, a digital printing process, a multicolor foiling process and a multi-color flocking process can be enabled to provide for a variety of designs and colors, dissimilar to the conventional method enabling a simple design and a single color work. The method of the invention is carried out with the pile put into a box and tightly contact at the top and bottom thereof and therefore the pile is not scattered into the atmosphere, thereby enabling to maintain a comfortable working environment, unlike the conventional process in which a pile is to be sprayed from the top to the bottom during the flocking process and thus a fine pile is scattered into the atmosphere to contaminate the environment of the workplace. The method is not an integral (fixed) type and thus can be carried out a selective work for each individual process, thereby improving the productivity by more 100-150% as compared to the conventional facility. Sixth, the movable pallet is formed of a thin aluminum plate of 3-4 mm thickness to minimize the time required for heating and cooling and to provide for easy attachment and detachment due to its light weight, and the pallet is supported on a pallet bracket to thereby avoid bending or distortion. | 12-23-2010 |
