Fuel cell system with preferential oxidation reaction and hydrogen separator
A recently granted patent (Publication Number: US11949135B2) discloses a fuel cell system that includes a first fuel cell with a first anode and cathode, a first oxidizer for preferential oxidation reaction, a second fuel cell acting as an electrochemical hydrogen separator, and a condenser for separating water and CO2. The system also includes a compressor for liquefying the CO2 output from the condenser, a second oxidizer for oxidizing a portion of the hydrogen stream, and a heat exchanger for transferring heat from the oxidized hydrogen stream to a cathode inlet stream. Additionally, the system features multiple heat exchangers and CO shift reactors to optimize the efficiency of the fuel cell system.
Furthermore, the patent describes a method for processing fuel cell exhaust, involving receiving the first anode exhaust gas at a first oxidizer, electrochemically separating hydrogen in the oxidized gas at a second fuel cell, and outputting a hydrogen stream. The method also includes a condenser for separating water and CO2, a compressor for liquefying the CO2, and multiple heat exchangers and CO shift reactors to enhance the overall process efficiency. Additionally, the method involves cooling the oxidized gas in a heat exchanger before feeding it to the second anode and transferring heat from the oxidized hydrogen stream to a cathode inlet stream. Overall, the patented system and method aim to improve the efficiency and performance of fuel cell systems by optimizing various processes involved in fuel cell operation and exhaust treatment.
