An electrically controlled pump (20) for dispersing a volatile substance into a local environment includes an enclosure defining a volume, a moveable member (52) separating the enclosure into first (54) and second (56) chambers (the second chamber containing non-solid composition which includes a volatile substance), an electrochemical cell (48) for generating gas. The electrochemical cell is associated with the enclosure, and is in fluid communication with the first chamber. A port preferably communicates the second chamber with a medium for dispersing the volatile substance into the local environment. Also, a case (58) may encase the pump and hold it in an upright position with respect to a surface upon which the case is positioned.

[ What is claimed is:] [1.] A method of dispersing a volatile substance into a local environment from an enclosure having a volume and first and second chambers, said first and second chambers sealedly divided by a displacement member fixed therebetween, said displacement member flexible within said enclosure, said second chamber containing a non-solid composition comprising the volatile substance, said method comprising:electrochemically generating gas into the first chamber thus moving the displacement member, compressing the second chamber, and displacing said non-sold composition out of said second chamber via an outlet in fluid communication with the local environment associated with said second chamber, thus dispersing the volatile substance into the local environment.
