4 Basic Operational principles Cathode reaction: ½ O 2 + 2e - = O 2- Electrical Energy (e - ) Anode reactions: H 2 + O 2- = H 2 O + 2e - CO +O 2- = CO 2 + 2e - C n H 2n+2 + (3n+1)O 2 = nco 2 + (n+1)h 2 O + (6n+2)e -

5 Internal reforming proceeds through the water produced by the fuel at the anode

6 ADVANTAGES CH 4 +H 2 O CO+3H 2 H 2 +O 2- H 2 O+2e - H 2 is directly produced in the SOFC H 2 is readily oxidized for the production of electricity DISADVANTAGES The exposure of the anode in high CH 4 /H 2 O may result in C deposition Low CH 4 /H 2 O ratios cause a decrease in the cell s Nerst potential Objectives Internal Methane steam reforming reaction Development of anode electrocatalysts active for catalytic CH 4 steam reforming and resistive to graphitic carbon formation and sulphur poisoning
