Method for continuously producing multiphase fluid flow

The invention relates to a method for continuously producing a multiphase fluid flow, in particular in the operation of a fuel cell, comprising the following steps: a) providing a multiphase fluid flow having a gas phase and a liquid phase, the gas phase having a carrier material and a process material, the liquid phase having a process material, and the process material being in the gas phase; the invention relates to a method for producing a multiphase fluid stream, comprising the steps of: a) introducing the multiphase fluid stream into a continuously operable rotating separator, c) at least partially separating the liquid phase from the multiphase fluid stream by means of the rotating separator in order to produce a produced fluid stream having a produced gas phase, the produced gas phase having a carrier material and a process material, wherein the proportion of the amount of material of the process material in the prepared gas phase is 50% or more of the proportion of the amount of material of the proce
