Abstract: A combustion section includes a casing that defines a diffusion chamber. The combustion section further includes a combustion liner that is disposed within the diffusion chamber and that defines a combustion chamber. The combustion liner is spaced apart from the casing such that a passageway is defined between the combustion liner and the casing. The combustion section further includes a fuel cell assembly that is disposed in the passageway. The fuel cell assembly includes a fuel cell stack having a plurality of fuel cells. The plurality of fuel cells extend from an inlet end in fluid communication with the diffusion chamber to an outlet end extending through the combustion liner and in fluid communication with the combustion chamber.

Abstract: A bottle opening sealer with an indicator window includes an outer cup, an inner cup, a sealing mechanism, a window, and a plurality of indicators. The sealing mechanism includes a lever, a connector, and an elastic sleeve. The inner cup is radially enclosed by the outer cup as the connector is axially positioned to the inner cup and the outer cup. The connector is slidably traverses through the outer cup and the inner cup. The elastic sleeve is positioned within the inner cap and slidably engaged around the connector. The lever is externally positioned to the outer cup and hingedly mounted to the connector about the outer cup. The window is laterally integrated onto the outer cup. The plurality of indicators is radially connected onto the inner cup, wherein each of the plurality of indicators is selectively displayed through the window.
