The purpose of this paper is to design a fuzzy control system for
generating hydrogen at a desired level by a reaction between water and
activated aluminum particles. The activated aluminum particles are
produced shredded aluminum sawdust. It is difficult to characterize the
reaction quantitatively because the characteristics of hydrogen
generating reaction vary as depending on the samples, the environment of
the reaction and so on. The experimental system consists of a fuel cell
(FC) of 100[W], a water tank, a reaction vessel, pressure sensors, a
water pump, a radiator and a one-chip microcomputer. The fuzzy control
system is designed to determine the quantum of water which is supplied
to the activated aluminum particles. The error forms a desired value of
the pressure of the reaction vessel and the change of the error are
chosen as the labels of the fuzzy membership functions. The proposed
fuzzy control system is applied to maintain the pressure of the reaction
vessel of the developed hydrogen generation system at a certain level.
The developed hydrogen generation system is confirmed to provide
hydrogen to the FC by experiments under various conditions.
