Title: A fuel cell including an electrolyte layer and a hydrogen permeable metal layer
Inventor: OGINO SHIGERU
IPC: H01M8/04
Filed: 2004-12-16
Abstract: A fuel cell of the invention has a hydrogen permeable metal layer, which is formed on a plane of an electrolyte layer that has proton conductivity and includes a hydrogen permeable metal. The fuel cell includes a higher temperature zone and a lower temperature zone that has a lower temperature than the higher temperature zone. The hydrogen permeable metal layer includes a lower temperature area A corresponding to the lower temperature zone and a higher temperature area B corresponding to the higher temperature zone. The lower temperature area A and the higher temperature area B have different settings of composition and/or layout of components. This arrangement effectively prevents potential deterioration of cell performance due to an uneven distribution of internal temperature of the fuel cell including the hydrogen permeable metal layer.

Abstract: A method of refurbishing a liquefied petroleum gas cylinder (13) characterised by fitting a tubular sleeve member (11) to the cylinder (13) between the footing (21) and the guard member (15). The sleeve member (11) is formed of a stretchable material which when unstretched is of height less than the surface distance along the surface of the cylinder (13) from the location of the guard (15) circumference to the location of the footing (21) circumference. The sleeve member (11) has a circumference of less than the maximum circumference of the cylinder, and has a top elastic member (27) attached at one end and a bottom elastic member (29) attached at the other end. The top elastic member (27) is in use, located proximal to the location of said guard (15) circumference and the bottom elastic member (29) is in use located proximal to the location of said footing (21) circumference. The top elastic member (27) is of a length when relaxed less than said guard circumference, and said bottom elastic member (29) is of a length when relaxed less than said footing circumference. This draws in the sleeve member (11), ensuring a smooth fit to the cylinder (13).
