“…Moreover, the surface wind speed is determined by vehicle and fan speeds and measured by the experiment. The relationship between the surface wind speed and vehicle and fan speeds obtained by the experimental data fitting can be represented in the form below: 𝑣 𝑤 = 0.1568 + 0.0015846 × 𝑛 fan + 0.02233 × 𝑣 (10) where 𝑣 𝑤 is the surface wind speed, m/s; 𝑛 fan is the fan speed, rpm; 𝑣 is the vehicle speed, km/h. When the ambient temperature and the radiator size are determined, the cooling capacity is determined by the surface wind speed and coolant flow rate, and the relationship can also be measured by the experiment.…”

“…Therefore, the component selection can be conducted according to specific requirements. For the control algorithm/strategy, Mohamed et al [10] proposed a thermal management control algorithm to control the operating temperature of each stack in the MFCS. In their algorithm, the excess heat quantity produced by the operating stack could preheat the next stack.…”

The performance of a fuel cell stack is affected by the operating temperature of the stack. The thermal management subsystem of a multi-stack fuel cell system (MFCS) is particularly significant for the operating temperature control of each stack in the MFCS. To study the influence of different topologies of a MFCS thermal management subsystem, this paper proposes and establishes two different topologies. Firstly, the integrated topology is proposed. Secondly, seven component models, namely the mixer, thermostat, radiator, tank, pump, bypass value, and proton exchange membrane fuel cell stack temperature models, are described in detail. Finally, the performance of the two topologies of the MFCS thermal management subsystem under two working conditions, steady (200 A) and variable (China heavy-duty commercial test cycle, C-WTVC), is compared. Furthermore, there are two evaluating indicators, including the stability duration and deviation of the operating temperatures of the single stack in the MFCS. Results show that when the MFCS operates under steady working conditions, the integrated topology is superior in operating temperature control accuracy (ΔT < 0.5 K), while the distributed topology is superior in the adjustment process (t ≤ 100 s). Moreover, when the MFCS operates under variable working conditions, the distributed topology is superior in operating temperature control accuracy.

“…Becherif et al [ 35 ] proposed an adaptive control strategy for regulating the FC temperature at the optimum point. Becherif and coworkers [ 36 ] proposed a multistack system installed in parallel with a battery, the idea was to use an adequate number of equivalent FCs to meet the required power. Ahmaditaba et al [ 37 ] conducted a pilot study of the bubble moisturizer used to moisturize PEMFC.…”

Pollution, global climate change, and the scarcity of fossil fuel reserves have forced the automotive industry to step up its research efforts on clean fuel cell electric vehicles (FCEVs). In fact, these systems can be considered relatively pollution‐free systems, with zero greenhouse gas emissions and higher efficiency than traditional vehicles. FCEVs typically use two sources of energy, fuel cells (FCs) and supercapacitors (SCs). One of the main issues with FCs is keeping the temperature between 60 and 90 °C. Herein, a strategy for controlling the temperature of the FC is proposed. Its objective is to achieve two main goals: the first is reducing the time and energy required to reach the optimum temperature, and the second is maintaining the temperature of the FC in the ideal range during operation. A Simulink/MATLAB model is established to determine the efficiency of the proposed system. The results show that at low ambient temperatures, the FC can be heated within 6 min, moreover the system allows cooling the FC and keeping its temperature in the ideal range.

“…Multi-stack can be considered as an attempt to increase the lifetime and durability of the fuel cell system at the cost of compactness loss. The multi-stack can be used for high power [13][14][15], vehicular and transportation [16][17][18][19][20][21][22][23][24], and stationary [16,[25][26][27] applications due to its higher reliability and efficiency and its optimized fuel consumption. This technology has been already used by a Mercedes bus, power supplies of space exploration vehicles, and air-independent propulsion for submarines [28].…”

To deal with the intermittency of renewable energy resources, hydrogen as an energy carrier is a good solution. The Polymer Electrolyte Membrane Fuel Cell (PEMFC) as a device that can directly convert hydrogen energy to electricity is an important part of this solution. However, durability and cost are two hurdles that must be overcome to enable the mass deployment of the technology. In this paper, a management system is proposed for the fuel cells that can cope with the durability issue by a suitable distribution of electrical power between cell groups. The proposed power electronics architecture is studied in this paper. A dynamical average model is developed for the proposed system. The validation of the model is verified by simulation and experimental results. Then, this model is used to prove the stability and robustness of the control method. Finally, the energy management system is assessed experimentally in three different conditions. The experimental results validate the effectiveness of the proposed topology for developing a management system with which the instability of cells can be confronted. The experimental results verify that the system can supply the load profile even during the degradation mode of one stack and while trying to cure it.
