<p>Provided are a microfluidic device for electrochemically regulating a pH of a fluid and a method of regulating a pH of a fluid using the microfluidic device. The microfluidic device includes a chamber including a cathode electrode formed of a metal adsorbing hydrogen gas, and an anode electrode formed of a metal having a higher standard oxidation potential than water and does not react with water, wherein gas is not generated in the chamber. In the microfluidic device, gas is not generated during electrolysis, and thus problems which may arise due to gas bubbles, such as interruption of flow of a solution, fluid control, mixing, reaction, and transfer of a material, such as heat, etc. do not occur. In addition, a gas outlet and an additional degassing device are not required, which contributes to minimizing the microfluidic device. According to the pH regulating method, a pH of a fluid in the microfluidic device can be quickly and easily regulated without generation of gas during electrolysis.
