AB  - 2-Propanol/acetone is a promising liquid organic hydrogen carrier system for fuelcell reactions. Herein, six different concepts for a 2-propanol/acetone fuel cellsystem are evaluated in MATLAB simulation with respect to their thermodynamicintegration and technical feasibility. Four of the concepts use a direct 2-propanolfuel cell while the other two first release molecular hydrogen from 2-propanol andsubsequently use a hydrogen fuel cell. The presented liquid phase 2-propanol fuelcell concept is thermodynamically feasible but cannot be realized technicallyusing commercial Nafion membranes, due to membrane dissolution by the2-propanol/acetone/water fuel mixture. Gaseous 2-propanol fuel cells imply a highheating requirement for the evaporation of the fuel. A direct high-temperature fuelcell using 2-propanol is thermodynamically feasible because there is less water inthe overall system but is not technically feasible because of the esterification ofphosphoric acid. A very interesting option is the conversion of gaseous 2-propanolto pressurized hydrogen in an electrochemical pumping step followed by ahydrogen fuel cell, because here the waste heat of a sufficiently hot hydrogen fuelcell can drive the 2-propanol evaporation.
