<P>PROBLEM TO BE SOLVED: To provide a catalyst-carrying carbon, its manufacturing method, pasted for electrode production, and a membrane-electrode assembly which can be easily manufactured and can attain high output, wherein ionic functional groups of a polymer solid electrolyte are apt to orient at a carbon particle side. <P>SOLUTION: The catalyst-carrying carbon prepares powder made of carbon particles 1 such as carbon black as shown in Fig.1a, and carries metal fine particles 1a (Fig.1b). Furthermore, oxide fine particles 1b made of oxide such as SnO<SB>2</SB>, Al<SB>2</SB>O<SB>3</SB>, ZnO<SB>2</SB>, and SiO<SB>2</SB>are carried by metal fine particles carrying carbon 2. Thus, the catalyst-carrying carbon 3 can be attained (Fig.1c). <P>COPYRIGHT: (C)2011,JPO&INPIT |
