Fuel Cell Information Sites & Consortiums

Class 1: Overview of SOFC

Read some of the general sites above.  Think about:

  • What is a fuel cell?
  • What is a SOFC and how is it different from H fuel cells being researched for cars?
  • What does a cross section of a SOFC look like?
  • How does a SOFC operate?
  • What are the advantages of a SOFC?
  • Why are ceramics used?
  • Why are nanomaterials use?

Class 2: Introduction to Ceramics in SOFC

Read Callister 12.1-12.2 and 13.8-13.11 and think about

  • How do you calculate the coordination number from the ionic readius?
  • Review the crystal structure for rock salt, CsCl, and zinc blende.
  • Review how the coordination number determined the crystal structure as shown in Table 12.4.

From Chapter 13, review the definitions of

  • Annealing
  • Sintering
  • Slip casting
  • Tape casting

Class 3: Ceramic Defects

Read Callister  4.2, 4.5-4.7 and 12.5 and review the definitions for:

  • Vacancy
  • Interstitial
  • Self-interstitial
  • Electroneutrality
  • Frenkel defect
  • Schottky defect
  • point defect
  • line defect
  • grain boundary

Class 4: Diffusion via defects

Read Callister 5.1-5.2, 5.5-5.6 and review the definitions for:

  • vacancy diffusion
  • interstitial diffusion
  • diffusion coefficient
  • fast paths for diffusion

Think about

  • How does the diffusion rate change if you increase
    • the temperature
    • the vacancy concentration'the amount of grain boundaries
  • When in a SOFC operation do you have diffusion?
  • Why do SOFC operate at high temperatures?

Read Callister 13.10 and thin about

  • What is the role diffusion plays in sintering (Figure 13.14)?

Class 5 & 6: Ceramic Phase Diagrams

Read Callister 9.1-9.15

Review the definitions for

  • Component
  • Solubility limit
  • Isomorphous
  • Eutectic
  • Eutectoid
  • Solidus, liquidus, and solvus line
  • Invariant point
  • Congruent point
  • Lever rule

Think about

  • Using Figure 9.6, identify the equilibrium phases and their compositions at various temperatures.  Use the lever rule to determine the fraction of each phase present
  • Study the figures in section 9.11 and understand the microstructure as a function of temperature
