AFC
1.AFC design
1.AFC design
Correctly label the diagram for alkaline fuel cell,including the anode ,cathode and electrolyte.
2.AFCprinciple
Oxidation:
2H2(g)+4OH-(aq)→4H2O(l)+4e-
Reduction:
O2(g)+2H2O(l)+4e-→4OH-(aq)
2H2(g)+O2(g)→2H2O(l)
3.AFC applications
What are theAFCapplications?
PEMFC
1.PEMFC design
1.PEMFCdesign
Correctly label the diagram for alkaline fuel cell,including the anode ,cathode and electrolyte.
2.PEMFCprinciple
Oxidation:
H2(g)→2H+(aq)+2e-
Reduction:
O2(g)+4H+(aq)+4e-→2H2O(l)
2H2(g)+O2(g)→2H2O(l)
3.PEMFC applications
What are thePEMFCapplications?
in buses
DMFC
1.DMFC design
1.DMFCdesign
Correctly label the diagram for alkaline fuel cell,including the anode ,cathode and electrolyte.
2.DMFCprinciple
Oxidation:
2CH3OH(aq)+2H2O(l)
→2CO2(g)+12H+(aq)+12e-
Reduction:
12H+(aq)+12e-+3O2(g)→6H2O(l)
2CH3OH(aq)+3O2(g)→2CO2(g)+4H2O(l)
