[0086] In an embodiment of the invention, the reactor module 1 has a central exhaust channel 2 and four flow channels 3 parallel to the exhaust channel 2. The exhaust channel 2 and the flow channels 3 extend in an axial direction 4. The reactor module 1 comprises four reaction chambers 5, which extend in a radial direction 6 at an angle of 90 degrees to each other. In each reaction chamber 5, an electrode plug 7 is aligned with the axis of the cylindrical reaction chamber 5 aligned with the radial direction 6 of the reactor module 1. The electrode plugs 7 are insulated by an insulating ring 24. The reaction chambers 5 are connected 8 to the exhaust channel 2. The reaction chambers 5 are connected to the flow channel by a tangential channel 9, which is connected to the reaction chamber in the tangential direction of its circular cross section. The flow channel 3 connects the distal side 10 of the reactor module with the proximal side 11 of the reactor module.

[0087] In an embodiment of the invention, the reactor stack 12 consists of five reactor modules 1 stacked axially (according to the axial direction 4). The exhaust channels 2 and the flow channels 3 of each reactor module 1 are connected between the reactor modules 1, thus forming interconnecting exhaust channels 13 and interconnecting flow channels 14. The reactor stack 12 is provided with a pressure chamber 15 which serves the function of gas injection into the interconnecting flow channels 14 and is suitable for distributing a flow of reaction gas 16 to any reaction chamber 5 in the reactor stack 12.

[0088] In this embodiment, the pressure chamber 15 is axially stacked (according to the axial direction 4) at the distal side 10 of the most distal reactor module in the stack of reactor modules. The pressure chamber 15 is donut-shaped with a cylindrical opening 16 having a circular cross-section of the same size as the circular cross-section of the interconnecting exhaust channel 13. The interconnecting exhaust channel 13 thus extends in the axial direction 4 through the pressure chamber 15, and the exhaust product 17 and the reaction gas 18 are separated by the inner wall 19 of the pressure chamber 15.

[0093] Example 1: Reactant and product gas flow calculations Example 1 refers to flow calculations performed on a reactor stack according to an embodiment of the present invention. The results show that the flow velocity varies from 5 to 30 m / s. Also, the vortex flow streamlines in the reaction chamber are calculated.

[0094] The flow patterns reveal gas distribution and vortex formation in the reaction chamber. Although no preferential flow has been observed in the five stacks, preferential flow may occur in longer stacks. In such cases, the vertical channel diameter should be increased.

[0095] For better illustration, reference is made to FIG. 5 which shows flow velocity streamlines obtained from flow calculations of a reactor stack according to an embodiment of the present invention.
