| 英文摘要 | a simple and effective method for reactivation of h2s poisoned pt-anodes is described and the feasibility of the method was examined by single cell tests and 1 kw stack tests. the performance of the h2s poisoned pt-anode can be basically recovered by applying a high voltage pulse (1.5 v for 20 s) followed by a low voltage pulse (0.2 v for 20 s) in a single cell. during the 10 poisoning-recovery cycles, the ohmic resistance and electrochemical surface area did not change significantly. the i kw stack tests show that the stack performance decayed severely and the maximum power decreased to 0.366 kw (32% of the original value) after exposure to 18 ppm h2s/h-2 for 2 h at 600 ma cm(-2). the stack performance can be significantly recovered by applying a high voltage pulse (1.5 v for 2 min) followed by a low voltage pulse (0.2 v for 2 min) to each cell. the maximum power recovered to 1.095 kw (97.5% of the original value).
