SOFC Base Test with EBZ IPM

EBZ supplies components for the air and gas preheating of the staxera Integrated Stack Module (ISM). Stack oriented experiments like performance and durability tests under steady or transient conditions can be carried out with the EBZ IPM. In system related tests, a detailed investigation of stack performance in dependence on fuel utilization and load is possible. The IPM supports the finding of optimal operation points by systematically varying of cathode air and fuel inlet temperatures.
