* The performance information for the gas-to-gas units are expressed as the flow rate of air (slpm) in relation to the approach dew point temperature. The approach temperature is defined as the difference between the cathode exhaust stream entering the humidifier and the humidifier exhaust stream going to the stack. For example, if the cathode exhaust dew point entering the humidifier is 67° and the humidifier generates a dew point of 61°, it would have been sized for a 6° approach temperature.
