FIELD: engines.
SUBSTANCE: invention relates to systems of cooling fuel cells. Cooling system for a fuel cell, comprising a main heat-transfer-fluid circuit including a circulation pump and a heat exchanger with exterior, which feed an upstream pipe supplying fluid to cells of fuel cell, said fluid leaving cells via a downstream pipe in order to return to circulation pump, characterised in that main circuit comprises a three-port controlled valve on each upstream and downstream pipe, third available port of upstream pipe being connected to inlet of pump and third available port of downstream pipe being connected to outlet of pump in order to establish a secondary fluid circuit.
EFFECT: technical result is fast starting at low temperatures.
