“…Thus, it shows great significance to systematically investigate the dynamic behavior during different stages of external load changes, and the relevant influential factors. The present work attempts to experimentally survey the dynamic characteristics and transient responses of PEM fuel cells under various load changes, and determine the relationship of the dynamic behavior and the operating parameters by employing a commercial PEM fuel cell stack of Ballard Nexa module that has been widely used by other research groups for different purposes [33][34][35][36][37]. Furthermore, the fully developed experimental data can be utilized for model validation in R&D work and facilitate establishment of efficient control and management strategies.…”

“…Alternatively, separate cooling plates can be added with channels made for air to flow through. Many systems have been reported using air cooling by simple use of a single fan to supply the air [83][84][85]. Elevated air flow rate is helpful for water management in air-cooled stack.…”

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.

“…However, this technique can generate high thermal gradient inside the fuel cell, especially at high loads. Experiments have shown differences up to 23 C between the inlet and the outlet of a cooling channel and up to 10 C between channels [1]. One way to increase the performance of the cell is by reducing the temperature difference between the inlet and outlet of the cooling channels.…”
