Abstract: The carrier metal catalyst achieves suppression of internal resistance of a fuel cell. A carrier metal catalyst includes: a carrier powder; and metal fine particles supported on the carrier powder; wherein: the carrier powder is an aggregates of carrier fine particles; the carrier fine particles includes a chained portion structured by a plurality of crystallites being fusion bonded to form a chain; the carrier fine particles include titanium oxide; the carrier fine particles are doped with an element having a valence different from a valence of titanium; the titanium oxide of the carrier powder has an anatase phase/rutile phase ratio of 0.2 or lower; the metal fine particles have a mean particle size of 3 to 10 nm; the metal fine particles include platinum; and a cell resistance measured under standard conditions of a fuel cell prepared using the carrier metal catalyst is 0.090 ?cm·2 or lower.

Abstract: A door structure for a vehicle capable of increasing its capability of protecting a passenger on the vehicle without increasing the thickness of the pad. The door structure is provided with a door body including an inner panel and an outer panel, reinforcements secured to each of the panels and a pad attached to the inner panel to protect the passenger. In the longitudinal direction of the vehicle, each of the reinforcements has its rear end positioned in front of the passenger. Because each panel has a higher rigid part with the reinforcement and a lower rigid part without the reinforcements, when an external force is exerted on the door body, it begins to deform in the vicinity of the rear end of the reinforcement, whereby it is possible to absorb the energy of the external force efficiently without injuring the passenger.

Abstract: A door for automotive vehicles comprises an inner panel formed with a work opening in a position corresponding to a door pad. The work opening has a front edge positioned ahead of a front end of the door pad, a rear edge positioned behind a rear end of the door pad, and an upper edge positioned above an upper end of the door pad. The door pad has a lower edge inserted into a groove at the bottom of the door.

Abstract: A wire harness supporting structure in a door according to the present invention includes a reinforced bracket having a guide and a pair of harness holders projecting upward from the guide. The reinforced bracket is fastened jointly with a doorlock to the internal part of the door. The wire harness extended from the electrical part is laid along the guide and fixed and supported at the harness holders.
