An electroosmotic flow pump capable of producing a strong liquid feed force especially over a long range of a channel, a pumping system employing that electroosmotic flow pump, a microchemical chip and a fuel cell. In the electroosmotic flow pump where at least a partial surface of a channel (15) for feeding liquid is formed of a dielectric (11), electrodes (14a, 14b) are arranged on one and the other sides in the extending direction of the channel (15) with respect to the dielectric (11), and the liquid is fluidized by applying a voltage between the electrodes (14a, 14b) on one and the other sides with respect to an electric double layer appearing between the liquid and the dielectric (11), the dielectric (11) is located on the bottom face of a recess formed in the inner surface of the channel (15), and the electrodes (14a, 14b) on one and the other sides are arranged oppositely at the opposite side faces of the recess opposing each other in the extending direction of the channel (15). |
