  • Patent number: 11476476
    Abstract: A fuel cell system includes a plurality of electricity generation systems and a connection flow path through which fuel flows between the plurality of electricity generation systems. Each electricity generation system includes a fuel tank, a fuel cell stack, a fuel flow path, a first pressure sensor, a shutoff valve, a control device, and a branch portion. The first pressure sensor is arranged in the fuel flow path and detects a fuel pressure on the fuel tank side. The shutoff valve is arranged on a downstream side of the first pressure sensor in the fuel flow path, and is switched between flow and shutoff of the fuel by opening and closing. The branch portion branches from the fuel flow path on a downstream side of the shutoff valve in the fuel flow path. The connection flow path connects the mutual branch portions of the plurality of electricity generation systems.

  • Publication number: 20050220376
    Abstract: A multi-bag comprises a multi-film made by superposing at least an inner film and an outer film and sealing the cylindrically curved superposed region to form a back seal. The multi-film constituting the multi-bag is a double film formed by flattening a tube-like film into a two-layer form, with the opposite end edges, which are parallel with the direction of extrusion, continuing to each other. The multi-bag is formed in a sealed state by a back seal, a planar seal at one end, and a planar seal at the other end. The supply system for the multi-film may be such that one system is prepared for each double so as to simplify the device. Further, in the film supply process, it is possible to obtain a multi-bag of high quality without applying a shift-preventive means to between the multi-films.
