Abstract
A fuel cell sensor is provided for detecting the presence of acetylene and hydrogen in a fluid. The sensor includes a sensing element having first and second gas diffusing electrodes spaced from one another. The first gas diffusing electrode can be used for sensing acetylene. The second gas diffusing electrode can be used for sensing hydrogen. A fuel cell spacer having an acidic electrolyte is disposed between the sensing element and a common electrode. The sensing element can be configured to have a specific ratio of the area between the first gas diffusing electrode in relation to the area of the second gas diffusing electrode.
