DMFC

The direct methanol fuel cell (DMFC) converts methanol as liquid fuel directly into electric current. In comparison to fuel cell systems operated with pure hydrogen or hydrogen-rich gases from reforming processes, the fuel is supplied directly via liquid methanol. Apart from the very high energy density of methanol, the DMFC is easy to handle and unproblematic to refuel.

The fact that the use of direct methanol fuel cells (DMFCs) appears to be interesting within the foreseeable future for small mobile applications, for example in the area of material handling as an alternative to lead-acid batteries, prompted IEK-3 to prioritize investigations and developments in this area. Other R&D activities on direct methanol fuel cells concentrate on developing DMFC systems in the kW class for emergency power supply – an application that is particularly challenging in terms of stack durability. Robotics is yet another interesting application for DMFCs. Systems in this area are characterized by a compact structure and a high power density.
