Fuel cell sensor is easy to be poisoned. How does the ASENSOR gas sensor deal with it?
The poisoning of a fuel cell sensor generally refers to a decrease of sensitivity after a significant amount of carbon monoxide is in contact with the sensor. This phenomenon frequently happens to the sensor using pure platinum as electrocatalyst. By contrast, the ASENSOR’s gas sensor employs platinum alloy as electrocatalyst that eliminates CO poisoning.Another situation similar to sensor poisoning is a decrease of sensitivity when the sensor is exposed to high concentration target gas. This problem is solved with diffusion control design.
