General Readings on SOFC
Web Tutorials
Technical Articles
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
