Consider a hydrogen-oxygen fuel cell, an electrochemical cell that generates electricity from the chemical reaction 2 H2(g) + O2(g) → 2 H2O(l) . Yes, this is the same reaction as in additional question 1, but now we are looking at electrochemical aspects of it. On one side of the cell, H2 is pumped in, and the half-cell reaction is 2 H2(g) + 4 OH–(aq) → 4 H2O(l) + 4 e– ; at the other side, O2 is pumped in: O2(g)...

In the spontaneous chemical reaction of an electrochemical cell, electrons flow from the anode to the cathode. 3. Increasing the activity of a reactant in the cell's chemical reaction must increase the cell potential. 4. If we double all the coefficients in a cell's reaction, the number of electrons transferred, n, is doubled but the cell potential is unchanged. 5. The...
