A polymer electrolyte fuel cell includes a cell stack (51) formed by stacking cells (11), each of which includes: an MEA (5) having a polymer electrolyte membrane (1), and an anode (4a) and a cathode (4b) sandwiching the polymer electrolyte membrane (1); and an anode separator (6a) and a cathode separator (6b) disposed to sandwich the MEA (5), an anode gas internal supplying channel is formed to supply a fuel gas and air to the anode (4a), and a CO removing catalyst layer (61) containing a CO removing catalyst is formed in the anode gas internal supplying channel.
