Claim Text:
1. A fuel cell, comprising: at least two stacks of electrochemical cells and end plates configured to apply a tightening strain to the at least two stacks of electrochemical cells; and a heat management system including an inside circuit configured for flowing a coolant into each of the at least two stacks, both of the at least two stacks being connected in parallel, and an outside circuit configured for flowing the coolant outside the at least two stacks, the outside circuit comprising a first subcircuit including a heat exchanger and a second subcircuit directly connected to an inlet of the inside circuit, and devices configured to control flow of the coolant to either or both of the first and second subcircuits as a function of temperature of the coolant at an output of each stack of the at least two stacks, and the heat management system further including a device configured to ensure that head losses of the first outside subcircuit and the second outside subcircuit have a deviation of 20% or less compared to a predetermined value.
