  "textContent": "The invention relates to a fuel cell system and a method for operating the same where the fuel cell system comprises a fuel cell (1) with a fuel processing portion (1.1,2,3) which comprises an anode (1.1) with a fuel feed line (2) to feed fuel to the anode (1.1) and an anode exhaust line (3) for removing anode exhaust from the anode (1.1) and an oxidant processing portion (1.2,4,5) which comprises a cathode (1.2) with an oxygen feed line (4) to feed oxygen to the cathode (1.2) and a cathode exhaust line (5) to remove cathode exhaust from the cathode (1.2), a water collecting unit (9) for extracting water from the cathode exhaust, wherein at least one heat exchanger (7,19) is arranged in the oxidant processing portion (1.2,4,5). One portion of said heat exchanger (7,19) is in thermal contact with a coolant of a fuel cell cooling circuit (10) of said fuel cell and another part of said heat exchanger (7,19) is in thermal contact with the oxidant or a fuel cell exhaust for cooling the oxidant and/or the fuel cell exhaust. Below the freezing point of product water generated in said fuell cell (1) a by-pass circuit (14,16) is employed to shut off a coolant flow to said heat exchanger (7,19).",
