PP-III-55been previously fixed and maintained for all the tests, in order to achieve a fastloading of the soot trap and guarantee the same initial conditions to all experiments.Hence, the system has been shifted to defined conditions and the regeneration effectmonitored.765Dp [mbar]43210.450.480.500,0 0,5 1,0 1,5time [h]Fig.1: effect of lambda on the regeneration of the soot trap performing the systemat 8 kW of thermal load.A number of results as those depicted in Fig. 1 (effect of lambda on regenerationspeed) have been gathered. These results indicate feasibility of an easy and practicalsolution for small-scale CHP applications based on fuel cells, requiring effectiveremoval of soot with no use of oxygen for safety and anode stability reasons.References[1].
