Title: Electrode catalyst for fuel cell and its manufacturing method
Inventor: KATO HISAO
IPC: H01M8/04
Filed: 2002-10-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electrode catalyst having an excellent CO poisoning resistance.  <P>SOLUTION: Relation between CO poisoning resistance and quantity of oxygen contained in Pt-Ru alloy is noted. This is because a Pt-Ru alloy has a high affinity with oxygen and once the Pt-Ru alloy is in oxidized state, it is estimated that it is difficult to return to metallic state under PEFC operation conditions. When Pt and Ru are in the oxidized state, their electronic states may be changed, which will affect the properties of the catalyst. As a result of examination of the oxygen content in the electrode catalyst for a fuel cell on the effect of catalyst activity, it was found that CO poisoning resistance is improved if the oxygen content is less than 4.4mass%. Based on the findings, this electrode catalyst for a fuel cell has a carrier, and a catalyst layer having a Pt-Ru alloy carried by the carrier, with the oxygen content less than 4.4mass%.  <P>COPYRIGHT: (C)2004,JPO

IPC: H01L29/78
Filed: 2002-10-16
Abstract: <P>PROBLEM TO BE SOLVED: To prevent interruption of power supply to normally operating MOS (metal-oxide semiconductor) transistors due to temperature rise attributable to an abnormally hot MOS transistor when a plurality of MOS transistors are housed in one and the same package.  <P>SOLUTION: Temperatures sensed for MOS transistor 21, 31 are compared with their thresholds in comparators 400a, 400b, respectively. When one of the comparators 400a, 400b decides that its MOS transistor is abnormally hot, its output is latched by a latch circuit, and power supply to the abnormally hot MOS transistor is interrupted. Further, the output of the comparator making the abnormally-hot decision switches over the threshold in the other comparator to a higher-temperature threshold, and this ensures that no abnormally-hot decision is made for the other MOS transistor which is in normal operation. The threshold switchover continues only for a specified period of time using a timer circuit.  <P>COPYRIGHT: (C)2004,JPO
