A carbon monoxide treatment apparatus according to an exemplary embodiment of the present invention includes: a reactor body; a partitioning plate located inside the reactor body for partitioning an internal space of the reactor body into a first section and a second section; a channel member in the first section for transporting an introduced gas including a reformed gas and an oxidant gas to the second section; and a reaction unit around the channel member of the first section for reducing a concentration level of carbon monoxide in the introduced gas moving through the first section by utilizing a preferential oxidation reaction of the carbon monoxide and the oxidant gas of the introduced gas, wherein moisture of the introduced gas that has been partially condensed when passing through the channel member is stored in the second section.
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.
