Fluid delivery apparatus and method

An apparatus for delivering a fluid, said apparatus comprising:

• a housing;
• a displaceable membrane disposed within said housing, dividing a portion of said housing into a first chamber and a second chamber, said first chamber formed in part, of said housing, said first chamber for containing fluid for delivery and having a port in fluid communication with said first chamber, and said second chamber for containing a driving gas, said displaceable membrane being impermeable to the driving gas;
• a pump for pressurizing driving gas in said second chamber, thereby exerting a force on said displaceable membrane, thus expelling fluid contained within said first member from said port, said pump comprising an electrochemical gas generation cell;
• and
• means for delivering fluid from said port to a desired location.
