“…These values represent the increase of activation energy as a function of temperature and at a constant pressure for the ORR as a consequence of membrane and ionomer dry-out in the presence of a Nafion electrolyte. This may be assumed as a baseline to establish the progress beyond the state of the art for the novel ionomers for automotive applications [44]. In fact, beside the increase of conductivity and performance in the intermediate Fig.…”

“…The comparison of different cooling channel geometries and flowfield designs through numerical simulations has received significant attention in the literature, including [11e14] among others. Chen et al and Baek et al [11,12] looked at the temperature distribution and pressure drop for different flowfield designs, Sasmito et al and Kang et al [13,14] also demonstrated how different configurations influenced the overall net power output of the fuel cell. To avoid significant thermal gradients across the cell, the change in liquid coolant temperature from inlet to outlet should be kept small [15,16].…”

“…Four volumes are considered in the model; anode, cathode, cathode inlet and cathode outlet manifolds. Equations (14)e (16) show mass balance equations for the cathode. In the evaporatively cooled model _ m H2Oinject represents the amount of water added to achieve a desired humidity within the cathode flow channel, this is calculated using a PI (proportional integral) controller to achieve a 100% target relative humidity.…”

Available online xxxKeywords: Thermal management Water balance Fuel cell vehicle PEM Heat transfer Cooling a b s t r a c tDespite having efficiencies higher than internal combustion engines, heat rejection from fuel cells remains challenging due to lower operating temperatures and reduced exhaust heat flow. This work details a full system simulation which is then used to compare a conventional liquid cooled fuel cell system to two types of evaporatively cooled fuel cell systems. Both steady state and transient operation are considered. Results show the radiator frontal area required to achieve thermal and water balance for an evaporatively cooled system with an aluminium condensing radiator is 27% less than a conventional liquid cooled system at 1.25 A/cm 2 steady state operation. The primary reason for the reduction is higher heat transfer coefficients in the condensing radiator due to phase change. It is also shown that the liquid water separation efficiency has a significant influence on the required radiator frontal area of the evaporatively cooled system.

“…They found that the high anode inlet relative humidity resulted in a lower anode exit temperatures and an increase in the cell voltage. Kang et al investigated the configuration of fuel, air, and cooling water paths in a PEMFC and how they influence its performance using a quasi-three-dimensional dynamic model [134]. Five different flow configurations were simulated to systematically investigate the effects of inlet flow conditions on each configuration.…”

Abstract:In an effort to reduce the environmental impact of the energy sector that is mostly based on fossil fuels, researchers are looking for a clean alternative of our existing energy sources. Hydrogen Energy and Fuel Cells, and in particular Polymer Electrolyte Membrane Fuel Cells (PEMFCs) have emerged as a leading candidate for transportation as well as stationary and portable applications. Due to the irreversibility of the electrochemical reactions and ohmic heating in the fuel cell components, the PEMFC produces a significant amount of heat and this heat has to be removed in order to avoid cell or stack overheating. In this paper, a review of the key heat transfer mechanisms and the various cooling strategies that are available for heat removal from PEMFCs are presented. Due to the interrelated nature and difficulty of conducting in-situ thermal measurements on the operating PEMFCs, computational modelling provides a fast and efficient way of designing PEMFC cooling systems and understanding the heat transfer mechanisms. Therefore PEMFC thermal modelling is also highlighted together with present challenges and potential areas for further research and development works.
