“…The combination provides adequate energy to auxiliary systems and to the EV. This solution can complement other researches on FC fault diagnosis [7, 8], identification [9], modelling [10–14] and functioning optimisation. However, technical inquiries concerning the heating of FC and which technology to use, diphasic or fluidic are outlined.…”

Automotive manufacturers face serious difficulties concerning the expected fossil fuel depletion and the emitted pollutants during combustion. The fuel cell (FC) vehicle is considered a promising solution for greener and sustainable transportation. The integration of FC in vehicles is limited by some technological constraints and technical barriers which can be partially met by splitting the power and energy into different 'downsized' FCs named multi-stack FCs. This study aims at proposing a multi-stack FC configuration for electric vehicles (EVs) to minimise its start-up time, heating/cooling and cycling problems. To properly reach such desired operating conditions, a novel thermal management technique is proposed. Using the modularity provided by multi-stack solution, each FC is activated depending on the FCs temperature and the required vehicle power. Simulation results, using MTCSim © software, demonstrate the capability of the proposed thermal management approach to effectively enhance the EV's multi-stack FC's life span, cycling and efficiency, besides optimising its operation performance.

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.

“…Benefiting from the parallel structure, a degradation operation can exclude the faulty stack from the multi-fuel cell system (MFC system). The stack is replaced when a stack fails (Becherif et al, 2015). The multistack association appears as a natural and necessary alternative for developing high-power fuel cell systems.…”

In high-powered application scenarios, a multi-stack fuel cell system (MFCS) could have advantages such as higher robustness, lifetime, and reliability than a single-stack fuel cell system. In particular, MFCS could maintain a high efficiency and increase system redundancy by power configuration between subsystems. In order to reduce the operational expenses for systems, a reasonable power management strategy is necessary to minimize the hydrogen consumption of MFCS. First, the power-hydrogen consumption curve of the single-stack fuel cell system is discretized from experimental measurements. Next, the discrete data are reassembled by the inverse derivation of the dynamic programming method to produce a minimum solution for the hydrogen consumption in the output power range. It is found that the strategy varies depending on activated state On or Off. Finally, two power allocation strategies are developed and modeled in a lookup-table block considering the activated state. The optimal stack output power strategy is analyzed with four stacks. The results indicate that the hydrogen consumption is smaller and more efficient than the other allocation strategies. It can respond to the load demand with a high efficiency sooner than the average strategy.
