The present disclosure relates to solid oxide fuel cells (SOFCs) exploiting gas separation devices in which a first gas mixture including components A (for example hydrogen) and B (for example carbon dioxide) is to be separated so that a first product of the separation is enriched in component A, while component B is mixed with a third gas component C (for example air, oxygen-enriched air or oxygen-depleted air) contained in a displacement purge stream to form a second gas mixture including components B and C, and with provision to prevent cross contamination of component C into the first product containing component A, or of component A into the second gas mixture containing component C. The invention may be applied to hydrogen (component A) enrichment from fuel cell anode exhaust, where dilute carbon dioxide (component B) is to be rejected such as to the atmosphere by purging with cathode exhaust oxygen-depleted air (as component C).

Heat exchange may be further improved by configuring the manifold to have a plurality of interleaved anode and cathode gas supply chambers.

The invention relates to a cooking method for a household appliance. According to the method, in the boiling point judgment stage, the bottom temperature is kept to be T4 which is 110-120 DEG C; a top temperature sensor is used for detecting the top temperature; a master control chip is used for presetting a sampling time t; the master control chip is used for presetting the sampling time t1 once again if the rising range of the top temperature is more than delta T in the sampling time t, and t1 is the difference between t and delta T; and the master control chip is used for saving the value of the top temperature to be a boiling temperature point T0 if the rising range of the top temperature is less than delta T.
