| Applications for SOFC Solid
oxide fuel cells are suitable for stationary and for mobile applications. Stationary
plants for the cogeneration of power and heat are in the development for different
sizes of residential buildings and also for large buildings and for industrial
or commercial applications. Heat can be gained at a high
temperature range and therefore can be used as process heat. Apart
from that big power stations on the basis of SOFCs are in the development stage.
In this case the waste heat is used for the power generation in gas turbines.
In future this type of power plant is to reach efficiencies of up to 70%. With
regard to mobile applications SOFCs at the moment are not developed for drive
trains but as a substitute for vehicle batteries. The reason for this is on the
one hand the constantly increasing number of devices requiring electric power
in cars and on the other hand the possibility to have electric power at ones disposal
for a long time - even when the engine is not operating. As fuel serves gasoline
which has to be converted in a simple reformer and also has to be desulfurised. |
