1. A method for continuously treating multiphase fluid flows during the operation of fuel cells, comprising the steps of:
a) providing a multiphase fluid flow comprising a gas phase and a liquid phase, wherein the gas phase comprises a carrier substance material and a process substance, wherein the liquid phase comprises the process substance, wherein the process substance is water,
b) introducing the multiphase fluid flow into a continuously operable rotating separator,
c) at least partially separating the liquid phase from the multiphase fluid flow by means of the rotating separator to produce a treated fluid flow comprising a treated gas phase, wherein 98% by weight or more of the liquid phase are separated,
wherein the treated gas phase comprises the carrier substance and the process substance, wherein a molar fraction of the process substance in the treated gas phase is 50% or more of a respective molar fraction of the process substance in the gas phase of the multiphase fluid flow.
