There is no flow of cooling water moving through it. Therefore the cell temperature can be used as is, either with reference to a calibration or the Stefan-Boltzmann law (or both). You can use the cell temperature to determine heat output when you use flow calorimetry. You can use it in addition to the inlet and outlet cooling water temperatures. However, the cell temperature varies with the flow rate, so if the flow meter malfunctions and you do not realize that the flow rate has changed, you will get the wrong answer for both methods. Both the cell temperature and the cooling water inlet and outlet temperatures will give the wrong answer. The answers are likely to diverge, which warns you that something is wrong. This happened to me in studies with Mallove and others. - Jed
