Abstract
A humidity sensing device for determining the amount of humidity in at least one primary fluid stream that is passed to a fuel cell stack is provided. The sensing device includes an outer housing and an inner housing. The outer housing is positioned within at least one conduit such that the outer housing and the conduit coact with each other to generate at least one secondary fluid stream from the primary fluid stream. The inner housing is positioned within the outer housing such that the inner housing is configured to receive the secondary fluid stream and to measure an amount of water present in the secondary fluid stream to determine the amount of humidity in the primary fluid stream.
