Conservation Of Energy

A heat transfer model of PEMFC is developed that captures dynamic behavior for control purposes in this paper. According to the law of conservation of energy, by analyzing in detail the heat source, considering the heat of electrochemistry, activation polarization heat and the heat loss of air forced convection etc., the dynamic heat model of PEMFC is established. Among all influential factors of fuel cell temperature, current density is one of the most important influence factors. Finally, by comparing the response results temperature with the current density changes between simulation and experiments, the results s are consistent. The model in this article has an important guiding significance for the design of fuel cell. For example, the working temperature of fuel cell can keep up stability by controlling cooling medium flow rate etc.

The Relationship

Pressure drop on the cathode side of a PEM (Proton Exchange Membrane) fuel cell stack has been studied and used as a diagnostic tool. Since the Reynolds number at the beginning of the flow field channel was <250, the flow through the channel is laminar, and the relationship between the pressure drop and the flow rate is linear. Some departure from linearity was observed when water was either introduced in the stack or produced inside the stack in the electrochemical reaction. By monitoring the pressure drop in conjunction with the cell resistance in an operational fuel cell stack, it was possible to diagnose either flooding or drying conditions inside the stack.
