A method of continuously subjecting an elongated substrate to vacuum film formation is disclosed. The method comprises the steps of: feeding a first substrate from a first roll chamber in a first direction from the first roll chamber toward a second roll chamber; degassing the first substrate; forming a film of a second material on the first substrate, in a second film formation chamber; and rolling up the first substrate in the second roll chamber, thereby producing the first substrate, and comprises similar steps to produce a second substrate. In advance of producing the first substrate with the second material film, the first cathode electrode of the first film formation chamber is removed from the first film formation chamber, and, in advance of producing the second substrate with the first material film, the second cathode electrode of the second film formation chamber is removed from the second film formation chamber.

Vacuum film formation method and laminate obtained by the method

The film formation method comprises the steps of: unrolling and feeding an elongated substrate wound in a roll form from a first roll chamber in a direction from the first roll chamber toward a second roll chamber, using a first surface as a surface for film formation; degassing the fed substrate; forming a first material film on the first surface of the degassed substrate in a first film formation chamber; forming a second material film on the first material film in a second film formation chamber; taking up the substrate in a roll form in the second roll chamber, the substrate having the material films formed thereon; unrolling and feeding the taken up substrate from the first roll chamber in the direction, using a second surface opposite the first surface of the substrate as a surface for film formation; and repeating all the above treatments.

Method for double-side vacuum film formation and laminate obtainable by the method

The film formation method comprises the steps of: unrolling and feeding an elongated substrate wound in a roll form from a first roll chamber in a first direction from the first roll chamber toward a second roll chamber, using a first surface as a surface for film formation; degassing the substrate fed in the first direction; forming a second material film on the first surface of the substrate in a second film formation chamber; taking up the substrate in a roll form in the second roll chamber, the substrate having the second material film formed thereon; unrolling and feeding the substrate from the second roll chamber in a second direction from the second roll chamber toward the first roll chamber; forming a first material film on the second material film in a first film formation chamber; taking up the substrate in a roll form in the first roll chamber.

The film formation method comprises the steps of: unrolling and feeding an elongated substrate wound in a roll form from a first roll chamber in a first direction from the first roll chamber toward a second roll chamber; degassing the fed substrate; forming a first material film on a first surface in a first film formation chamber; guiding the substrate having the first material film formed thereon to a second film formation chamber in a second direction from the second roll chamber toward the first roll chamber; forming, in the second film formation chamber, a second material film on a second surface opposite the first surface of the substrate when it is being guided in the second direction; taking up, in a third roll chamber provided between the first roll chamber and the second roll chamber, the substrate in a roll state.

A fuel cell, a method for operating a fuel cell and a fuel cell system, which ensure no dew condensation for a wet reaction gas in the inlet area of gas channels in plates in a fuel cell stack, are provided. Gas channelsand heat medium channels are disposed on one surface and the other surface of one plate, respectively. Gas channels are disposed on the other plate such that they face the gas channelsin the plate. A gas inlet headeris disposed at the upper part of the gas channelin the plateand a heat medium inlet header is disposed at the upper part of the heat medium channels such that they face the gas inlet header on the other side. Cooling water such as heat medium is supplied from the heat medium supply manifold holeto the heat medium inlet header, thereby warming up the same. The water vapor in the reaction gas (wet fuel gas) is prevented from being condensed in the inlet area of the gas channelsby heating up the gas inlet header by the heat conduction.

Fuel cell, method for operating fuel cell and fuel cell system

A fuel cell system comprising a fuel cell having plural membrane-electrode assemblies and plates, fuel and oxidant humidifiers and heater exchanger. Heat exchange between a supply inlet and discharge outlet is carried out between first and second heat exchange mediums. Fuel gas and oxidant gas are directed to flow parallel to each other in the fuel cell. A circulation path is established through the fuel and oxidant humidifiers and the heat exchanger by interconnection among discharge outlet, heat exchanger, fuel and oxidant humidifiers, and inlet.

Gas channels are disposed on the other plate such that they face the gas channels in the one plate. A gas inlet header is disposed at the upper part of the gas channel in the plate and a heat medium inlet header is disposed at the upper part of the heat medium channels such that they face the gas inlet header on the other side. Cooling water as a heat medium is supplied from a heat medium supply manifold hole to a heat medium inlet header. Water vapor in the reaction gas (wet fuel gas) is prevented from being condensed in the inlet area of the gas channels by heating the gas inlet header by heat conduction.
