<P>PROBLEM TO BE SOLVED: To provide a catalyst for producing hydrogen for a fuel cell, which can be used stably even in a DSS (daily start-up and shut-down) operation of repeating the ON/OFF of the supply of fuel and to provide the DSS operation-correspondence fuel cell provided with the catalyst for producing hydrogen for the fuel cell. <P>SOLUTION: The catalyst for producing hydrogen for the fuel cell has the general formula expressed by an ABO<SB>3</SB>type (where B is a composition of Ni<SB>x</SB>Mn<SB>(1-x)</SB>; and x is 0.7±0.10). The catalyst for producing hydrogen for the DSS operation-correspondence fuel cell where the ON/OFF of the supply of fuel is repeated has the general formula expressed by an ABO<SB>3</SB>type (wherein B is a composition of Ni<SB>x</SB>M<SB>(1-x)</SB>). The composition of Ni<SB>x</SB>M<SB>(1-x)</SB>is characterized in that metal Ni is deposited on an oxycarbonic acid compound in the DSS operation. M of Ni<SB>x</SB>M<SB>(1-x)</SB>is preferably Mn and x is preferably 0.7±0.10. <P>COPYRIGHT: (C)2008,JPO&INPIT |
