A thin film deposition apparatus and a thin film deposition method using an electric field are provided. The thin film deposition apparatus includes: a first substrate; a plurality of electrodes in a 2D arrangement on the first substrate; and a solution provided on the plurality of electrodes and in which charged nanoparticles are distributed, wherein the charged nanoparticles are selectively deposited on at least a part of the plurality of electrodes by independently applying a voltage to each of the plurality of electrodes.

A monopolar cell pack for a direct methanol fuel cell is provided. In the monopolar cell pack, series-connection of electrodes makes it unnecessary for connections to pass through an electrolyte membrane and allows single cells to be electrically connected on the first and second surfaces of the ion exchange membrane, respectively, thereby preventing leakage of fuel. As a result, the internal electric circuit according to the present invention can be simplified. Also, since current collectors contact the anodes and cathodes entirely rather than partially, contact resistance can be considerably reduced, thereby greatly reducing a loss due to resistance. Carbon dioxide, which is a byproduct of the reaction, can be easily exhausted through an exhaust path installed in each current collector, thereby improving performance of a cell pack.
