Abstract: A technique that is usable with a fuel cell stack includes detecting an unhealthy condition of the stack, such as carbon monoxide poisoning, flooding, or fuel starvation, and implementing a recovery action to correct the detected condition. The technique further includes observing the response of the stack to the recovery action to distinguish between unhealthy conditions that have the same indications.

Abstract: A technique to shut down a fuel cell stack includes reducing an oxidant flow through the fuel cell stack, and decreasing the current of the fuel cell stack while maintaining an approximately constant rate of fuel flow to the fuel cell stack. Once the power output of the fuel cell stack reaches zero due to the depletion of oxygen at the cathode, the fuel flow to the fuel cell stack anode is then halted. Then, the stack is either isolated from the reactant streams, or the cathode is briefly purged by the fuel before the stack is isolated from the reactant streams, or both the anode and the cathode are purged in sequence by air before the stack is isolated from the reactant streams.

Abstract: A probe apparatus for use with analyzing devices, primarily oscilloscopes and logic analyzers, which uses pole-zero cancellation to provide a probe with low capacitance and wide bandwidth. Pole-zero cancellation enables the probe to have constant gain at all frequencies.
