... applications. The output fuel cell current is then submitted to the high frequency switching leading to a current ripple. The ripple current effects on fuel cell are studied by experimental ripple current aging test on a five cell stack (membrane electrode assembly (MEA) surface of 220 cm 2 ) and compared...

... on the compressor speed and/or the cathode back-pressure valve, allows to better take into account the effect of exogenous variables on stack performance. Particularly, the proposed technique has proven to perform better than classical feedforward/feedback approaches when well known aging mechanisms deteriorate...

... was used to simulate the performance of a half-cell SOFC with ( Pr 0.7 Sr 0.3 ) Mn O 3 ± δ ∕ 8 mol % yttria-stabilized zirconia (8YSZ) composite cathode on one side of the 8YSZ electrolyte before and after aging. Multiphysics phenomena in the SOFC were considered in the modeling. The current/voltage curves...
