Energetics of Technical Integration of 2‐Propanol Fuel Cells: Thermodynamic and Current and Future Technical Feasibility

2-Propanol/acetone is a promising LOHC (Liquid Organic Hydrogen Carrier) system for fuel cell reactions. In this paper six different concepts 2-propanol/acetone are evaluated in Matlab simulation with respect to their thermodynamic integration and technical feasibility. Four of the use direct 2-propanol while other two first release molecular hydrogen from subsequently cell. The presented liquid phase concept thermodynamically feasible but cannot be realized technically using commercial Nafion membranes, due membrane dissolution by 2-propanol/acetone/water mixture. Gaseous cells imply high heating requirement evaporation fuel. A high-temperature because there less water overall not esterification phosphoric acid. very interesting option conversion gaseous pressurized an electrochemical pumping step followed cell, here waste heat sufficiently hot can drive evaporation.
