Aiming to reduce global warming and emissions in general, cleaner technologies are the spotlight of research and industry development. Among them, fuel cell vehicles (FCV) are gaining interest to decarbonize the transport sector. Plug-in FCV or FCV in range-extender configuration (FCREx) is an interesting option to reduce the total cost of ownership (TCO) and the energy usage per km. The aim of this study was to generate design spaces of FCREx by varying the FC stack maximum power output, the battery capacity, and the H₂ tank capacity to understand the implications of this architecture in range, consumption, and cost (estimated with a WLTP driving cycle). Unlike other studies, the approach was focused on a novel architecture for passenger vehicles and was focused on the development of the validated FC system model and the energy management strategy (EMS) optimization for each design, based on the Pontryagin Minimum Principle (PMP). Consumption was found to decrease with increasing battery capacity and FC maximum power due to the higher efficiency of the systems. The design spaces showed how with 5 kg of H₂ and $\ge$50 kWh of battery capacity the maximum range of FCREx could be over 700 km. The results of this study showed how FCREx architecture could provide overall energy consumption saving up to 6.8% and H₂ consumption saving ranging from 16.8% to 25%, compared to current commercial FCVs. The optimum FCREx design, not only based on performance, should have $\sim$30 kWh of battery capacity and $\ge$80 kW of FC maximum power to minimize manufacturing costs while maximizing efficiency.

为了总体上减少全球变暖和排放，清洁技术是研究和行业发展的重点。其中，燃料电池汽车（FCV）引起了人们的兴趣，以使运输部门脱碳。增程配置（FCREx）的插入式FCV或FCV是降低总拥有成本（TCO）和每公里能耗的有趣选择。这项研究的目的是通过改变FC堆栈的最大功率输出，电池容量和H ₂来生成FCREx的设计空间。坦克的能力，以了解此架构在范围，消耗和成本方面的含义（以WLTP行驶周期估算）。与其他研究不同，该方法侧重于乘用车的新型体系结构，并侧重于基于庞特里亚金最小原理（PMP）开发经过验证的FC系统模型和每种设计的能源管理策略（EMS）优化。随着系统效率的提高，发现消耗随着电池容量和FC最大功率的降低而降低。设计空间显示了如何使用5 kg H ₂和$\ge$50 kWh的电池容量，FCREx的最大范围可能超过700 km。这项研究的结果表明，与目前的商用FCV相比，FCREX架构如何能够节省多达6.8％的总能耗，以及节省16.8％至25％的H ₂能耗。不仅基于性能，最佳的FCREx设计应具有$〜$30 kWh的电池容量和 $\ge$FC最大功率为80 kW，可最大程度地降低制造成本，同时提高效率。
