The solid oxide fuel cell has a positive-electrolyte-negative (PEN) structure. On the rear surface of the anode collecting layer there is a relief structure chosen to provide a series of channels for the circulation of gas. The cathode may also have a similar relief structure providing gas circulation channels. The electrical cell has a positive-electrolyte-negative (PEN) structure within a solid oxide fuel cell (SOFC). The cell includes a cathode comprising porous cathode layer (cpc) and an active cathode layer (cac), and an anode with an active anode layer (caa) and a support anode layer (csa, csa1, csa2). Between these is at least one electrolyte layer (e) placed between the active anode and cathode layers. The anode comprises an anode collecting layer (cca, cca1, cca2). On the rear surface of the anode collecting layer, which is intended to come into contact with an interconnection plate (i), there is a relief structure chosen to provide a series of channels for the circulation of gas. The cathode may also have a similar relief structure providing gas circulation channels. |
