 note = {The purpose of this study was to combine fuel cells with different operating temperatures into fuel cell cascade
systems in order to analyze their power generation efficiency and environmental impact (CO2 emissions). Nine fuel
cell cascade systems were investigated by numerical analysis. We also proposed the use of these systems in
microgrids. The power generation efficiency of a compound system containing a solid-oxide fuel cell, a micro-gas
turbine, a reformer, and a proton-exchange membrane fuel cell showed great improvement compared with simplex
operation of each component of the system. Moreover, a fuel cell cascade system can use alcohol fuels with low
CO2 emission factors. The fuel cell cascade systems tested showed that CO2 emission reductions are possible.
