The invention relates to a spectroscopy system and improved membrane formation techniques. The first and second heat transfer systems facilitate the discharge of ammonia gas from the vapor generation tank at a substantially constant flow rate and pressure. The impedance reference value is a reference value that is set in order to prevent the water content in a fuel cell from decreasing too much. When the cylindrical valve is rotated to a first position the first flow through aperture and the second flow through aperture are in register thereby permitting gas to flow through. may be presented in a variety of ways based on capabilities or properties of a device accessing the information or data.
