Abstract: Provided are a heat recovery apparatus based on a fuel cell and an operating method thereof. In the fuel cell-based heat recovery apparatus and the operating method thereof, hot water and steam may be generated by using heat generated while a molten carbonate fuel cell (MCFC) operates to supply the generated hot water or steam to buildings, thereby reducing a rate of operation in cooling/heating equipment using electricity so as to reduce air-conditioning costs.

Abstract: Provided are a method for manufacturing a polymer electrolyte membrane for a fuel cell, a membrane electrode assembly and a polymer electrolyte membrane fuel cell. The manufacturing method includes (S1) forming a plurality of grooves on a substrate; (S2) casting an ion exchange resin solution for forming an electrolyte membrane on a surface of the substrate having the plurality of grooves; (S3) drying the ion exchange resin solution to form a polymer electrolyte membrane; and (S4) separating the formed polymer electrolyte membrane from the substrate. The ion conductive electrolyte membrane manufactured by the method has the grooves formed on the surface thereof, so that a contact area with a catalyst is maximized to improve the performance of the fuel cell, and adhesion of electrodes and the electrolyte membrane is improved to enhance the interface stability with the electrodes.

Abstract: A diagnostic and analytical apparatus including the microfluidic device having: an inlet portion with a first cross-section, a flow delaying portion with a second cross-section that is larger than the cross-section of the inlet portion thereby reducing the interfacial curvature of the microfluid entering from the inlet portion by capillary force and the flow rate of the microfluid, and a flow recovery portion having a third cross-section that is smaller than the cross-section of the flow delaying portion. The flow of a very small volume of fluid can be quantitatively regulated through a channel having a particular design that can induce spontaneous flow by capillary force without additional manipulation processes and energy requirement.
