Abstract: A fuel cell comprising a reaction chamber; a plurality of capillary tubes configured to permit a fuel component to flow there through, the capillary tubes being arranged in bundles in adjacent segments within the reaction chamber; a plurality of electrodes, at least one of the plurality of electrodes passing through each of the plurality of capillary tubes, being against each of the plurality of capillary tubes, or passing through and being against each of the plurality of capillary tubes; and a plurality of counter-electrodes, Each electrode extends beyond ends of its respective capillary tube, and electrodes associated with capillary tubes of a segment are electrically connected to one another at each end at substantially the same electrical potential. Each segment has a wall section to which is attached at least one of the counter-electrodes or wherein the wall section at least partially forms at least one of the counter-electrodes.

Abstract: A method for distilling ethanol from a mash includes feeding a fluid to a first distillation column. The fluid and a distillate of the first distillation column are delivered to a second distillation column. The fed fluid and/or distillate of the second distillation column is/are purified in a first and/or last step of the method by a membrane separation process.

Abstract: A feed stream is fed to a first distillation stage comprising at least one distillation column (stripper) and the distillate from the first distillation stage is fed to a second distillation column (rectifier). The feed stream is sub-divided into two streams and fed to two distillation columns, in such a way that the rectifier maintains a predefined energy balance.

Abstract: In order to increase the output of a fuel cell, the fuel cell has an electrode arrangement comprising a number of series-connected electrode bundles (1-6), each consisting of a number of parallelly connected electrodes (7) and each being electrically connected and captive at the ends.
