| 摘要 |
A fuel cell is disclosed, comprising an anode part (11) with an inlet and an outlet for a fuel, for example, hydrogen; a cathode part (14) with an inlet and an outlet for an oxidising agent, for example, oxygen and a membrane (17) situated between the anode part and the cathode part. According to the invention, a limited differential pressure across the membrane between the anode and the cathode part, under all operating conditions is achieved, whereby a spring-loaded pressure regulator (20) is arranged in the fuel outlet and a membrane-controlled pressure regulator (30) is arranged in the oxidising agent outlet. The both pressure regulators are coupled to each other, by means of a connecting line (40) linking the regulating chamber of the pressure regulator with a pressure chamber of the pressure regulator. The pressures in the anode part and the cathode part can thus be held the same under all working conditions. |
