    摘要： A fuel cell system includes a fuel supply unit for supplying fuel, an air supply unit for supplying air, a coolant supply unit for supplying coolant, and a stack having an electricity generator in which separators are disposed on both surfaces of a membrane-electrode assembly so as to generate electric energy through an electrochemical reaction between hydrogen and oxygen supplied from the fuel supply unit and the air supply unit. The stack includes a plurality of cooling channels through which a coolant is supplied from the coolant supply unit. The cooling channels include contact-area extension surfaces for increasing the contact area of the coolant in order to provide improved cooling efficiency.

    摘要： A fuel cell system optimizing the ratio of width of a channel to a width of a rib forming a passage for supplying fuel and air, the ratio of width thereof to a height of a channel, and the number of passages, thereby improving the fuel diffusing performance and reducing a pressure drop therein is provided. The fuel cell system includes at least one stack for generating electrical energy by an electrochemical reaction between hydrogen and oxygen, a fuel supply portion for supplying fuel to the stack, and an oxygen supply portion for supplying oxygen to the stack. The stack is formed into a stacked configuration having a plurality of membrane electrode assemblies separated by separators. The separators have ribs which closely contact the adjacent membrane electrode assemblies and form channels through which the oxygen and hydrogen flow. The ratio of the width of a channel to the height of the same is between about 0.6 and about 0.8.

    摘要： Disclosed is a fuel cell system wherein the flow of fuel and oxygen is optimized thereby improving the thermal efficiency of the entire system. The fuel cell system comprises at least one stack for generating electrical energy by an electrochemical reaction between hydrogen gas and oxygen, a fuel supply portion for supplying fuel to the stack, and an oxygen supply portion for supplying oxygen to the stack. The stack is formed in a stacked configuration with MEAs and separators. The separators are positioned on either surface of the MEAs. The separators have a plurality of ribs proximate to the MEAs which define a plurality of channels wherein the ratio of a width of the channels to the width of the ribs is from about 0.8 to 1.5.
