Answer: as copper has lower electrode potential value than hydrogen, it could be reduced by hydrogen.
Explanation: hydrogen has zero reduction potential while Cu has +0.34V and Al has -1.66 V .
SO in electrochemical series who has most negative or less reduction potential value tends to be a good reducing agent than the other.
Hope it helps...

- It's all to do with the reactivity series
Copper is below hydrogen in the reactivity series
Thus it can reduce copper by taking the oxygen from it
However, aluminium is above hydrogen in the reactivity series so it wouldn't be possible.
