A solid oxide fuel cell has a reinforced membrane-electrode assembly. The solid oxide fuel cell includes a first electrode layer, a second electrode layer, and an electrolyte membrane disposed between the first and second electrode layers. The solid oxide fuel cell further includes a gas-permeable structure adjacent to one or both of the electrode layers, for mechanical stabilization.
