“…In order to facilitate the calculation of the PEMFC model, the assumptions adopted by the models are [17][18][19]: 1) PEMFC operates in steady-state; 2) The phase of all gas components is ideal and incompressible [20]; 3) The reactant gas in the flow field is regarded as laminar flow; 4) The GDL, catalytic layer, and proton exchange membrane are all isotropic; 5) The operating temperature of PEMFC is 80℃; 6) The gravity is ignored. The governing equations used to solve the PEMFC flow fields include the mass conservation equation, the momentum conservation equation, charge and species transport equations [21,22].…”

As a critical component, the bipolar plate appreciably affects the performance of proton exchange membrane fuel cell (PEMFC). The flow field structure on the bipolar plate is significant in transporting the internal reaction gas and excess water. In the nature, the leaf veins provide efficient branch networks to the plant, contributing to distribute the nutrients in the whole system. By bionic means, a similar branching structure can be used to design flow channels on the bipolar plates for PEMFC, which helps distribute the reactant gas evenly and manage the water better. In this paper, a three-dimensional isothermal single phase model of the bio-inspired flow channel design based on the leaf vein pattern was presented. The effect of the angle between the main channel and sub-channels on the performance of PEMFC was studied at various cases. A PEMFC of 10.24cm2 activation area was assembled and examined experimentally. The results showed that increasing the angle appropriately was beneficial to improving the uniform oxygen distribution and excess water removal. After comprehensively analyzing the electrochemical performance, species distribution, and power loss of PEMFC, the optimal angle was presented.

“…However, these non-destructive methods are difficult to implement in PEMFC stacks. Furthermore, previous studies [30][31][32] used numerous sensors and involved considerable calculation time to realize the same level of accuracy as the PCB method. Hence, installation and control in a PEMFC system are challenging.…”

Experimental investigation of stable the proton exchange membrane fuel cell control using magnetic sensor probes

In proton exchange membrane fuel cells (PEMFCs), the avoidance and detection of failures such as flooding and dry-out are crucial. Non-destructive measurement approaches using magnetic sensors have been developed for this purpose.To reduce the number of sensors required to be installed in a PEMFC system for evaluation, we propose a control method for PEMFCs using the magnetic flux density as an index. The proposed method determines the failure conditions by calculating a simple current mapping with a reduced number of sensors. The results of four-point magnetic flux densities under failure conditions and stable control using two-point measurement indices are presented.

Proton exchange membrane fuel cell is a clean energy generator as it emits water as a by-product. The fuel cell has various applications in stationary power generation and transportation. However, there is a need to improve durability for transportation applications. Fuel cell durability is limited as its performance degrades over a period due to aging, and fault conditions. In this study, we have compared fuel cell performance by using a new cell, and an aged cell. Degradation due to aging is experimented with by using a membrane that was operated for more than 2000 hours. Fuel cell performance degrades around 90% due to aging. Moreover, experimentally faults were created to study the degradation of fuel cell performance. We created three faults in the fuel cell system: Water flooding, reactant gas starvation, and high operating temperature. Fuel cell performance observed more than 30% degradation during the fault conditions. Furthermore, the coefficient of variance technique is used to detect aging, and the fault condition.
