摘要:
An apparatus is disclosed for testing the performance of a sealant for solid oxide fuel cell packs. The apparatus includes an oven including a base, a platform provided on the base and a frame connected to the platform. An elevator is used to raise and lower the oven. A pressuring and testing chamber is provided on the platform. The pressuring and testing chamber includes a first body and a second body connected to the first body. A carrier is provided between the first and second bodies. The carrier includes a first plate and a second plate so that the sealant can be provided between the first and second plates. A pusher includes an end connected to the frame and another end for pushing the second plate. A pusher-driving unit is connected to the frame for raising and lowering the pusher.
摘要:
Three bonding materials are provided on a first plate. The first bonding material is located between the second and third bonding materials. The first bonding material is thicker than the other bonding materials. A second plate is provided on the first bonding material. All of the plates and the bonding materials are heated to the softening point of the first bonding material. A load is exerted on the first bonding material to reduce the thickness of the first bonding material to that of the second and third bonding materials and transfer the load to the second and third bonding materials from the first bonding material. The temperature is raised to and kept at the crystallization point of the first bonding material. The temperature is raised to the wetting point of the second and third bonding materials.

A sealing material for solid oxide fuel cells is provided, which is composed of around 60% to 80% by weight of glass, around 20% to 30% by weight of alcohol, around 0.5% to 3% by weight of ethyl celluloid as a binder, and around 0.01% to 0.1% by weight of polyethylene glycol as a plasticizer.
摘要:
Disclosed is a laminate for use in a fuel cell. The laminate includes at least two field plates and a bonding layer. Each of the flow field plates includes a plate and channels defined therein. The bonding layer is made in the form of an annular strip and sandwiched between the flow field plates, around the channels.
摘要:
A method for manufacturing membrane electrode assembly of fuel cell includes positioning an ion exchange membrane that is cleaned and trimmed to a predetermined size in advance to a base plate, mounting the base plate to a printing platform, attaching a printing plate to the platform, coating a catalyst solution on the printing plate with a scraper, printing the catalyst solution onto the ion exchange membrane with the scraper, heating the ion exchange with a heating board to a temperature of 70–80° C., and waiting for the ion exchange membrane to return flat to complete the coating of the catalyst solution on the ion exchange membrane. The printing and heating steps are repeated for both anode and cathode of the ion exchange membrane. The ion exchange membrane is further subject to hot pressing and then a piece of carbon cloth is positioned on the catalyst coating to serve as a diffusion layer. This completes the manufacturing of the membrane electrode assembly.
