Abstract: Disclosed are methods and devices for producing very fine particles which are then coated with protective polymers in another step of the process. The particles are produced using a method in which a liquid flow comprising a particle-free liquid 1 that contains the active substance in a dissolved form is combined with a second liquid flow comprising a liquid 2 in a high-energy zone or no sooner than two seconds before reaching the high-energy zone. Said two liquids can be mixed with each other while the active substance dissolved in liquid 1 is insoluble or more difficult to dissolve in liquid 2 than in liquid 1 and settles in the form of particles in the high-energy zone or within a maximum of 2 seconds before reaching the high-energy zone when the two liquids are mixed. The obtained particles are introduced into an aqueous outer phase which contains the coating materials in a dissolved form and are then subjected to a drying step such that said materials settle on the particles as a closed coating.

Abstract: A method of operating a fuel cell system in a vehicle that is switchable to a temporary stop mode and restarted from the stop mode. When, in certain driving situations, it is required to switch to the stop mode, it is then checked whether the operating conditions of the fuel cell system allow a switch to the stop mode. If the switch is allowed it takes place. When a restart of the fuel cell system is required on the basis of the vehicle the settings of the stop mode are cancelled again. The switch to the stop mode involves, with further existing electric contacting of the fuel cell, the air mass flow conveyed by the air conveying device being switched off or reduced to a predefined value and the pressure of the combustion gas supplied being reduced to a predefined value.
