Solution

This type of electrochemical cells are called as concentration cell. There will be H+ ions in two different concentration and cathode reaction and anode reaction will be same
The left side of the cell diagram represents oxidationn part. So the anode reaction is Hydrogen is oxidized to H+ ions

Cathode reaction is H+ ions are reduced to H2

The overall reaction is
