and low dissolution rate to avoid precipitation of metal
Electrolyte :
lithium potassium carbonate
lithium sodium carbonate
Advantage :
no expensive electro-catalyst
CO can be fuel
waste heat allows the use of a bottoming cycle
Disadvantage :
very corrosive and mobile electrolyte
required CO2
high contact resistances and cathode resistance limit power density
- 동전위 분극 시험
icorr (μA/cm2) : corrosion current density
E.W. (Equivalent weight) = 1 / NEQ = 8.99
NEQ (total number of equivalent) = Σ (fi ni / ai )
- ai : atomic weight
- fi : mass fraction
- ni : electrons exchanged
Density (g/cm3) = 2.7

Objection
Metals, ceramics, polymers that represent material engineering can find easily in our real life. Compare corrosion degree in case of uncovered in same corrosion environment and corrosion difference inquires happened reason.
Consider how take advantage of Material in state that is more better in our real life.
