Mass Concentration Losses Flashcards
(4 cards)
1
Q
What are mass concentration losses?
A
The decreased concentration of reactant gases as they move through the flow channels of the electrode.
2
Q
What reactant do mass concentration losses typically apply to?
A
Oxygen. Since it is typically supplied in a mixture of air.
3
Q
In what case can mass concentration losses affect hydrogen?
A
When supplied as a reformed gas.
4
Q
Why are mass concentration losses affected at high current densities?
A
This is when the largest gradients exist in the flow channels.
