Disclosed is a membrane-electrode assembly having increased active area, improved fluid management capability, and decreased gas transfer resistance due to electrodes having patterned structures on both sides. Also disclosed are a method for manufacturing same, and a fuel cell comprising same. A membrane-electrode assembly according to the present invention comprises: a first electrode; a second electrode; and a polymer electrolyte membrane between the first and second electrodes, wherein the first electrode has a first surface facing the polymer electrolyte membrane and a second surface opposite the first surface, the first surface having a first patterned structure, and the second surface having a second patterned structure.

3D scanner

An infill apparatus and method for an output of a 3D printer, including a unit block generating part which slices a 3D model by using three planes orthogonal to each other to generate unit blocks; a unit block classifying part which classifies the unit blocks into boundary unit blocks and internal unit blocks according to positions thereof and classifies the boundary unit blocks into flat roof unit blocks and non-flat roof unit blocks according to whether or not a flat roof region is included; a combined block generating part which merges the internal unit blocks and generates a combined block; a flat roof point discriminating part which discriminates flat roof points in the combined block; a combined block dividing part which divides a part of the combined block including the flat roof points; and an infill shape determining part which determines a divided surface (or contact surface) of the combined block divided by the combined block dividing part as infill shape and outputs a printing material to the infill shape during outputting.

The present invention relates to a method for converting an image file or document file into a drawing file including the steps of extracting an outline from an image of a subject file to be drafted; detecting corner feature points from the image of the subject file to be drafted based on the extracted outline to coordinate the corner feature points into outer edge coordinate information and connecting the detected corner feature points with a line to generate a first image; removing the outline from the image of the subject file to be drafted and detecting one or more elements to coordinate the elements into element coordinate information and generating a second image including the one or more detected elements; template matching by superimposing the generated first image and second image; and generating a drawing file for the subject file to be drafted by using the outer edge coordinate information and element coordinate information.
