PURPOSE: To obtain a device simple in structure, easy to operate and inexpensive to produce by a method wherein the gas produced in an electrochemical cell part is introduced into the space of the device to increase its inner pressure so as to press a partition member, thereby supplying fluid from a fluid supply part to a fluid storage part.
CONSTITUTION: A fluid supply device (container body 1 and lid body 2) and an electrochemical cell part 8 for producing gas by application of DC current, are provided. The fluid supply device bodies 1 and 2 are provided with a partition member 3 deformable by the gas pressure, a first space 5 and a second space 6 defined by the partition member 3 and a gas introducing part 11 for introducing the gas produced at the electrochemical cell part 8 into the second space 6. The first space 5 is provided with a deformable fluid storage part 13 having a fluid supply part 15. By introducing the gas produced in the electrochemical cell part 8 into the second space 6, the inner pressure of the second space is raised to press the partition member 3, thereby supplying fluid from a fluid supply part 15 to a fluid storage part 13.
