Abstract
An electrochemical fluid delivery device of the present invention includes a case, pressure generating part and fluid reservoir part. The case has a cover capable of being opened and closed. When the cover is closed after the fluid reservoir part is accommodated in the case, the inside of the case can be maintained in an airtight condition. The pressure generating part includes a power supply part and electrochemical cell part. When a direct current flows in the electrochemical cell part, gas is generated and accumulates in the airtight case. By the pressure of gas, the fluid reservoir part is pressurized so that the fluid can be delivered. The amount of gas generated at constant pressure by the electrochemical cell part is determined by a quantity of electricity (current.times.time). Since the amount of fluid to be delivered is proportional to the amount of generated gas, the amount of fluid to be delivered in a unit time can be determined by the intensity of a current. A total amount of delivered fluid can be determined by the quantity of electricity.
