A planar solid electrolyte oxygen separator includes a first end plate formed with an oxygen outlet, a second end plate, two solid electrolyte cells disposed between the first and second end plates, and a planar interconnector disposed between the solid electrolyte cells. Each of the solid electrolyte cells includes two electrode layers, a metal-oxide-based electrolyte layer, and a through hole that is aligned with the oxygen outlet. The planar interconnector includes an upper portion having upper main channels and an upper passage, a lower portion having lower channels, and a connecting passage fluidly connected to the upper passage and the lower channels.

A stamping assembly includes an upper die, a lower die, first pins and second pins. Each of the upper and lower dies has columns of depressions and columns of guiding holes. Each column of the guiding holes is disposed between two adjacent columns of the depressions. The depressions of one of the upper and lower dies are registered with the guiding holes of another one of the upper and lower dies. The first pins and second pins are respectively positioned in the guiding holes of the upper and lower dies and extend outwardly. The first pins and the second pins are respectively arranged into first and second matrices.

Stamping assembly for preparing modular planar interconnect plate

A method for preparing a modular planar interconnect plate includes steps of a) providing a metal blank sheet having a main region and two first lateral regions, b) forming two openings respectively in the first lateral regions, and c) stamping to form protrusions and depressions at the main region on lower and upper surfaces of the metal blank sheet. In the stamping step, each of two lower surrounding protrusions and two upper surrounding depressions is formed to surround a corresponding one of the openings, and each of an upper surrounding protrusion and a lower surrounding depression is formed to surround the first lateral regions and the corresponding ones of the protrusions and depressions formed at the main region.

A modular planar interconnect device for a solid oxide fuel cell includes a planar interconnect body, a pair of upper shielding plates, and a pair of lower shielding plates. The planar interconnect body includes a right lateral surface and a left lateral surface. The right lateral surface includes a right lateral slot to fluidly communicate with an introducing slot of the planar interconnect body. The left lateral surface includes a left lateral slot to fluidly communicate with an exit slot of the planar interconnect body.

A thermally conductive silicone composition includes 25 to 50 volume % of a silicone, 30 to 60 volume % of a first heat conducting filler, and 20 to 40 volume % of a second heat conducting filler, and 1 to 2 volume % of a third heat conducting filler. The thermally conductive silicone composition has two heat conducting fillers with different sizes dispersed therein, thus the thermal impedance can be efficiently reduced.
