Title:
燃料電池システム
Document Type and Number:
Japanese Patent JP6707434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system in which the performance of a fuel cell stack when anode off-gas is re-used can be improved.SOLUTION: A fuel cell system 10A includes a separation unit 20 for separating at least one of carbon dioxide and steam from anode off-gas G3. In a first heat exchanger 30 and a double tube 50, heat exchange is performed between anode off-gas G3 and air A flowing into the separation unit 20, and the anode off-gas G3 and the air after heat exchange flow into the separation unit 20. The heat exchange between the anode off-gas G3 and the air A is controlled such that an optimal temperature T0, at which the function of a separation membrane 28 of the separation unit 20 is exhibited, is maintained.SELECTED DRAWING: Figure 1
