“…To guarantee a homogeneous coating over the cross-section, a cage-like anode filled with Ni pellets (Ampere GmbH, Dietzenbach, Germany), as described by Jung et al [12,13], was used. In contrast to the state of the art in fully coating OCAFs with nickel and nickel alloys [20,21,22] or with copper [23,24,25], the OCAFs in this work were only partially coated. Each partially coated OCAFs sample of 40×40×40 mm 3 was manufactured by submerging only half of the foam in the electrolyte and coating it with 50 µm Ni using a current density of 1.5 mA/cm 2 .…”
