To ensure a performance-based regulation of a fuel cell, the use of fuel- mixtures with a defined flow is required. According to the invention, to produce mixtures of this type, water is pumped through a hollow body, which, at least in certain sections, has a wall consisting of porous material and fuel is pumped into the chamber on the other side of the porous wall, at a defined flow rate. As a result of the difference in pressure, the fuel penetrates the porous wall over its entire surface into the water flowing pa st on the other side of said porous wall, thus creating a homogeneous mixture. In the corresponding device (10, 20), at least certain sections of the hollow body (1, 21) have a porous wall (2, 22). A device of this type is preferably used in direct methanol fuel cells (DMFC), for which the operating temperatu re and the operating pressure can be pre-defined. |
