Analysis of PEFC system with deuterated materials

Koizumi, Satoshi; Yamaguchi, Daisuke; Putra, A.

With using a big advantage of neutron, which can well distinguish the difference between deuteron and neutron, the distribution and transfer of water in an operating PEFC system was observed and analyzed by small-angle neutron scattering method. Concerning the operation of PEFC system by deuterium gas the efficiency increased by 5%. This is consistent with the calculation of free energy. The deuterium gas and deuterium oxide was also used for the labeling and distinction between the water generated by reaction and the water came from humidifier.
