摘要:
The present invention provides a method for producing an electrode catalyst for a fuel cell, comprising the steps of: mixing conductive particles loaded with catalyst metal fine particles with an organic compound; and heat treating the mixture formed in the mixing step under an inert gas atmosphere, so as to carbonize the organic compound. According to the present invention, the size increase of catalyst metal fine particles, which lowers catalytic activity, can be suppressed.

An object of the present invention is to provide a platinum catalyst for a fuel cell, the platinum catalyst having platinum particles with a fine particle size which are supported on carbon carriers in a highly dispersed manner. To achieve the above object, the present invention provides a method for producing an electrode catalyst for a fuel cell, the method comprising: an ammonia treatment step of heat-treating carbon carriers in an ammonia gas atmosphere; a platinum salt contact step of mixing the carbon carriers treated with ammonia with a solution prepared by dissolving a platinum salt in a solvent and bringing the platinum salt coming into contact with the carbon carriers in the mixture that has been formed; a recovery step of recovering the carbon carriers by removing the solvent from the mixture; and a heat treatment step of heat-treating the recovered carbon carriers in an inert gas atmosphere.

摘要:
The present invention aims to provide a corneal endothelium cell proliferation accelerator and a therapeutic agent for a disease relating to corneal endothelium damage, which are administered into the anterior chamber. bFGF is released in a sustained manner by forming bFGF sustained-release gelatin hydrogel particles wherein bFGF is carried on gelatin hydrogel. Therefore, the proliferation of corneal endothelium cells can be accelerated persistently by administration of a preparation containing the bFGF sustained-release gelatin hydrogel particles into the anterior chamber, and diseases relating to corneal endothelium damage can be treated.
