Reduction of potassium ion and hydrogen ion

I am studying a galvanic cell, and the cathode uses potassium hydroxide as its electrolyte. I am getting confused as to what gets reduced when electrons come from the anode.


I believe it would be the hydrogen ions (because the solvent is water) as potassium ion would never want to accept an electron (because it has a configuration of a noble gas as an ion and is therefore very stable). However, the pH of the solution would be very basic because KOH is the electrolyte; thus, the reduction potential value of hydrogen ion should also decrease.


Can someone please tell me what the right answer is?
