The sticking plaster does perform a couple of important roles in this design. It is "breathable," so it lets oxygen in so that it can react with the methanol. The gauze pad is absorbant and will hold a few drops of methanol solution, so you don't need a continuous feed of methanol to the anode.

Plus, holding together the other componoents is not exactly unimportant! For the cost of obtaining them, sticking plasters are tough and their adhesive is durable.
