摘要:
In a polymer electrolyte fuel cell of the present invention, at least one of electrodes comprises conductive carbon carrying a platinum group metal catalyst, conductive carbon carrying no catalyst metal and a hydrogen ion-conductive polymer electrolyte. The preferable amount of the conductive carbon carrying no catalyst metal is equivalent to 5 to 50 wt % of the conductive carbon carrying the catalyst metal. Incorporation of the conductive carbon carrying no catalyst metal to the catalyst layer enables reduction in potential concentration on part of electron conduction channels in an electrode, whereby an electrode for a polymer electrolyte fuel cell having an excellent life characteristic can be provided.

In a heat generation unit of the present invention, a holder having an elastic force tube used for holding a film-sheet-shaped heat generation element that generates heat upon application of a voltage thereto is disposed in a container together with the heat generation element. The heat generation element is held in a predetermined position in the container by the elastic force of the holder, with electric power being supplied from power supply members thereto through the holder, so that the heat generation element can be reliably held in the container, with a partial heat generation in the holder of the heat generation element being suppressed.

A magnetically floating carrier system has a carriage body which is adapted to be floated by the attraction force of floating magnets acting upon the bottom surfaces of rails. The carriage body is driven by a linear motor. The rails are mounted on a framework extending longitudinally to define a track and having one side thereof supported. The carriage body is provided with a support member extending upwards at the other side of the framework to a point above the top surfaces of the framework. A pallet for supporting a load is mounted on the top end of the support member so as to be disposed over the framework. The carriage carries four magnets at front and rear parts thereof which are adapted to exert a force of attraction on the pair of rails. The magnets are mounted at both ends of two beams mounted on front and rear parts of the carriage body for see-saw motions and steering motions.
