    摘要: A fuel cell system of the invention includes a tubular switching member 70 with slits 70a to shift their position and thereby vary an opening area of outlets of oxidizing gas conduits 36 in respective unit fuel cells 30 constituting a fuel cell stack 20. The system further includes a drive roller 74 and a stepping motor 79 that function to change over the position of the slits 70a. An electronic control unit controls rotation of the stepping motor 79 to actuate the tubular switching member 70 first to narrow the opening area of the outlets of the oxidizing gas conduits 36 to or toward 0 and then to widen the opening area of the outlets of the oxidizing gas conduits 36, thereby generating pulsation in the oxidizing gas conduits 36. Water droplets flocculated in the oxidizing gas conduits 36 are thus discharged to the outlets with high efficiency. The structure of the embodiment does not require any bypass in the respective unit fuel cells 30. The characteristic structure of the invention uses the frame of the unit fuel cell 30 equivalent to the existing one and does not substantially increase the size of the fuel cell stack 20.

    摘要: A catalyst for electrodes in solid-polymer fuel cells which comprises metal oxide particles themselves. It can be used as a substituent for the carbon particles having platinum deposited thereon and platinum metal particles which are presently in general use as, e.g., a catalyst for electrodes in fuel cells, and has a possibility that the amount of platinum to be used can be greatly reduced as compared with the conventional carbon particles having platinum deposited thereon, etc.The catalyst comprises fine transition-metal oxide particles having, in the main phase, a perovskite structure represented by the general formula ABO3 (wherein A represents one or more elements selected among lanthanum, strontium, cerium, calcium, yttrium, erbium, praseodymium, neodymium, samarium, europium, silicon, magnesium, barium, niobium, lead, bismuth, and antimony; and B represents one or more elements selected among iron, cobalt, manganese, copper, titanium, chromium, nickel, and molybdenum), the fine oxide particles having lattice constants satisfying the following relationship (1): 1.402

    摘要: A fuel cell includes a diffusion layer formed in a sheet having a small thickness. The fuel cell is assembled with a tension imposed on the sheet in an in-plane direction of the sheet. The tension is imposed on the diffusion layer from a frame disposed outside the fuel cell. The tension is of such a magnitude as to prevent a portion of the sheet positioned corresponding to a gas passage of a separator from being deformed when the fuel cell is assembled and has a tightening force thereby applied thereto. The tension is adjustable according to a fuel cell operating condition. These structures can prevent a separator rib from pushing into a membrane, maintaining the gas passability of the diffusion layer well.
