This invention relates to a solid oxide fuel cell system comprising at least one tubular solid oxide fuel cell and a combustion heater mounted in sufficient thermal proximity to the fuel cell that heat generated from combustion inside the heater is able to heat the fuel cell(s) to a suitable operating temperature. The heater and fuel cell can be encased within a tubular thermal casing; the inside of the casing defines a first reactant chamber for containing a first reactant, such as oxidant. The fuel cell comprises a ceramic solid state electrolyte layer and inner and outer electrode layers concentrically arranged around and sandwiching the electrolyte layer. The outer electrode layer is fluidly communicable with the first reactant, and the inner electrode layer is fluidly isolated from the first reactant and fluidly communicable with a second reactant, such as fuel.
H01M 8/1213 - Fuel cells with solid electrolytes operating at high temperature, e.g. with stabilised ZrO2 electrolyte characterised by the electrode/electrolyte combination or the supporting material
A method of reducing water influx into a wellbore, wherein the wellbore is in fluid communication with a subterranean formation such as a gas producing formation or gas reservoir. The method particularly places a gelant in a desired position down the wellbore and into the formation in order to thereby reduce the influx of water and enhance the resulting gas production. The method includes the steps of first introducing a gelant into the wellbore and second introducing a temporarily stable foam into the wellbore in order to overdisplace the gelant from the wellbore and into the formation.
A board suitable for use as container flooring uses bamboo and fast-growth low- density wood. Thin layers of high-density bamboo composites are used to overlay on surfaces of a core layer which can be the composite of wood veneer and wood strand-based composite, or wood veneer and bamboo stripe sheet composite. This invention combines the benefits of bamboo and wood materials to produce a bamboo-wood composite board having sufficient mechanical and physical strength and durability for use as container flooring.
