  We study stationary black brane solutions in the context of N = 2, U(1)
gauged supergravity in five dimensions. Using the formalism of first-order flow
equations, we construct examples of extremal black brane solutions that include
Nernst branes, i.e. extremal black brane solutions with vanishing entropy
density, as well as black branes with cylindrical horizon topology, whose
entropy density can be computed from a Cardy formula of the dual CFT.
