Abrégé
(EN)
Hydrogen in a fuel cell is vented and purged with a fail-closed valve using stored energy (e.g. from a capacitor) when a diagnostic parameter is outside of an acceptable operating range. The valve closes after the stored energy has depleted. A safety switch in the relay circuit of the solenoid switch (or solenoid valve) is also grounded in computer-implemented shutdowns. Benefits from the invention include use of air-compatible catalysts, minimized parasitic losses to power output, minimized contamination of fuel cell internal surfaces after venting, minimized risk of explosive mixture buildup, and efficient operation.

(ZH)

当诊断参数在容许的工作范围之外时,采用出故障时自动关闭的阀利用存储的能量(例如,来自电容器)排出和清除燃料电池中的氢。该阀在耗尽存储的能量之后关闭。电磁开关(或电磁阀)的继电器电路中的安全开关仍然通过计算机实现的关闭而接地。本发明的好处包括:使用空气可容性催化剂、使得功率输出的寄生损失最小化、使得排气后燃料电池内表面的污染最小化、使得形成爆炸性混合物的危险最小化以及能够有效地操作。
