Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.

The present invention provides a method for manufacturing a membrane-electrode assembly for a polymer electrolyte fuel cell, in which the glass transition temperature of an electrolyte membrane is reduced using a hydrophilic solvent, and a membrane-electrode assembly for a polymer electrolyte fuel cell, manufactured by the method. In the method of the invention, the glass transition temperature of the electrolyte membrane to which a catalyst is transferred is reduced compared to that in a conventional method for manufacturing a membrane-electrode assembly for a polymer electrolyte fuel cell using the decal process. Thus, even to an electrolyte membrane material having a relatively high glass transition temperature, the catalyst may be transferred at a rate of 100% at a temperature of about 120&#xb0; C., at which hot pressing is carried out. Thus, the problems associated with electrolyte membrane deterioration occurring in conventional methods can be solved.
