Abstract: An electrode system comprising: a plurality of first electrode plates (3) and a plurality of second electrode plates (5?) arranged alternatingly to form an electrode stack, each first electrode plate having a first electrode plate first busbar opening and a first electrode plate second busbar opening extending through the first electrode plate, the first electrode plate second busbar opening being larger than the first electrode plate first busbar opening, each second electrode plate (5?) having a second electrode plate first busbar opening (27a?) extending through the second electrode plate (5?), the second electrode plate first busbar opening (27a?) being dimensioned larger than each of the first electrode plate first busbar openings and aligned with the first electrode plate first busbar openings, and a second electrode plate second busbar opening (27b?) extending through the second electrode plate (5?), the second electrode plate second busbar opening (27b?) being dimensioned smaller than each of the firs

Abstract: A method of producing a gas mixture, said method comprising the steps of: a) subjecting water to electrolysis to obtain a hydrogen gas stream and an oxygen gas stream; b) reacting the hydrogen gas stream with solid carbon to obtain a stream comprising hydrocarbon gas, such as methane gas; and c) mixing the oxygen gas stream with the stream comprising hydrocarbon gas.

Abstract: A dual gas flow device including: a first cooling plate structure, a second cooling plate structure, a plurality of electrode plates, wherein the first cooling plate structure, the second cooling plate structure and the plurality of electrode plates are arranged in a stacked configuration, wherein the first cooling plate structure forms a first end of the stack and the second cooling plate structure forms a second end of the stack, wherein the plurality of electrode plates are arranged between the first cooling plate structure and the second cooling plate structure, wherein each electrode plate includes a plurality of cooling channels extending through the electrode plate, distributed along a peripheral portion of the electrode plate, each cooling channel being aligned with the corresponding cooling channel of the other electrode plates in the stack, wherein each of the first cooling plate structure and the second cooling plate structure is provided with a plurality of connecting channels, each connecting cha
