Control of Hydrogen Generation from Water Molecules Dissociated by Activated Aluminum Particles Based on Fuzzy Logic

This paper proposes a control system to keep hydrogen generation by a reaction between water and activated aluminum particles at desired level. Because the activated aluminum particles are produced shredded aluminum sawdust,the characteristics of hydrogen generation vary depending on its samples. Therefore,the fuzzy control system to determine the quantum of the activated aluminum particles is designed based on the measured characteristics of hydrogen generation. Error form a desired value,error rate and dead time of the reaction are chosen as the labels of the proposed fuzzy membership functions. The reactor vessel that the activated aluminum particles are put into is developed to generate hydrogen continuously. Three types of aluminum particles of the characteristic are used for the experiments. The proposed system is confirmed to be useful for the control of hydrogen generation,coping with the effect of reacting characteristic changes according to the activated aluminum samples.
