Current pulsing improves the performance of fuel cells in a fuel cell stack based power system. Voltage clamping limits the voltage peaks that occur after a current pulse. In a hybrid power system, an electric storage device supplies the loads during current pulsing. The electric storage device may sink current to achieve the voltage clamping, and/or power system may employ other the voltage clamping circuits.
La pulsation du courant améliore la performance de piles à combustible dans un système d'alimentation électrique basé sur des empilements de piles à combustible. Le calage de la tension limite les crêtes de tension qui se produisent après une impulsion de courant. Dans un système d'alimentation électrique hybride, un dispositif de stockage électrique alimente les charges pendant la pulsation du courant. Le dispositif de stockage électrique peut absorber du courant pour permettre le calage de la tension, et/ou le système d'alimentation électrique peut mettre en oeuvre d'autres circuits de calage de la tension.
