Abstract
To design a fuel cell system, solid-liquid equilibrium was measured for two binaries, benzene + toluene, benzene + methylcyclohexane, and a quaternary, benzene + cyclohexane + methylcyclohexane + toluene, by use of a cooling type apparatus. Hydrogen (H_2) solubility was also measured for four binaries, benzene + toluene, cyclohexane + methylcyclohexane, benzene + methylcyclohexane and cyclohexane + toluene, and a quaternary, benzene + cyclohexane + methylcyclohexane + toluene, by use of a synthetic type apparatus up to 5.000MPa at 303.15K. The H_2 solubility was increased linearly with the pressure following the Henry's law for all systems. Using the optimized binary interaction parameters, cubic equation of states well predicted the H_2 solubility for the quaternary.
