Vorrichtung und Verfahren zur Erhöhung der Brennstoffkonzentration in einem der Anode einer Brennstoffzelle zugeführten, einen Brennstoff enthaltenden Flüssigkeitsstrom und deren Verwendung

摘要

The invention relates to the field of fuel cell technology, more specifically to a device and a method for supplying fuel to the anode of a direct alcohol fuel cell. Said device comprises a fuel accumulator in which the fuel is stored, and a flow-through device provided with a wall at least partially consisting of a membrane that is permeable to the fuel. Said flow-through device is used to guide a mixture of a carrier constituent and the fuel through the fuel accumulator, and the concentration of fuel in the mixture is increased by the diffusion of fuel through the permeable membrane.
