TITLE

• SOLID OXIDE FUEL CELLS
• POLYMER WITH EXAMPLE

2
SOFC OPERATING PRINCIPLES

• FUEL IS DELIVERED TO THE ANODE AND
  OXIDANT,TYPICALLY AIR,IS DELIVERED TO THE CATHOD.
• THE ELECTRODE ARE SOLID POROUS STRUCTURES THAT
  ALLOW THE FUEL AND AIR TO THE ELECTROLYTE AND THE
  PRODUCT OF ELECTROCHEMICAL REACTION ON THE ANODE
  SIDE TO DIFFUSE AWAY FROM THE ELECTROLYTE.
• THE ELECTROLYTE CONDUCTS THE OXYGEN IONS FORMED
  BY THE ELECTROCHEMICAL REDUCTION OF MOLECULAR
  OXYGEN FROM THE CATHODE SIDE TO THE ANODE SIDE OF
  THE SOFC.

ADVANTAGES AND DISADVANTAGES

• ADVANTAGES

• DISADVANTAGES

• NO THERMAL EXPANSION MISMATCH PROBLEM
• FLEXIBILITY TO CHOOSE VARIOUS MIXED CONDUCTING
  OXIDE
• NO CHEMICAL REACTION PRODUCT AT THE
  CATHODE/ELECTROLYTE INTERFACE

• INTERDIFFUSION/CHEMICAL REACTIONS?
• LONG-TERM STABILITY.
• THE INTERMIDEATE LAYER DOMINATE ELECTROCHEMICAL
  PROCESSES.
• LIMITED NUMBER OF THE POSSIBLE SYSTEM.

• CONCENTRATION GRADIENT CATHODE/ELECTROLYTE
  COMPOSITE
• MULTI-LAYER CATHODE
• CHEMICALLY-STABLE CONCENTRATION-GRADIENT
  CATHODE/ELECTROLYTE COMPOSITE

POLYMER

• A POLYMER IS THE ANY OF A CLASS OF THE SYNTHETIC
  OR NATURAL SUBSTANCE COMPOSED OF VERY LARGE
  MOLECULES MOLECLUES, CALLED MAECOMOCELUES,WHICH
  ARE MULTIPLES OF SIMPLER CHEMICAL UNITS CALLED
  MONOMERS
