The present work examines the combination of solar energy systems with Fuel cell. Indeed, fuel cells are green storage systems without any pollution effects. They are supplied by oxygen and hydrogen to produce electricity. That is why it is inescapable to find a source of hydrogen in order to use fuel cell. Several techniques can be adopted to produce hydrogen depending on the availability and the cost of the sources. One of the most utilized techniques is electrolysers. They allow to obtain hydrogen from water by several technologies among them proton exchange membrane (PEM) which is considered in this work. On the other hand, electrolysers need electrical power to operate. A green-green energy system can be constructed by using a renewable energy source to supply fuel cell trough electrolysers. A comparison between two solar systems (Photovoltaic and Parabolic Trough) coupled to fuel cell is performed. A case study on the Lebanese city of Tripoli is carried out. The study shows the performance of each of both combined systems for different parameters and proposes recommendations depending on the considered configuration.

本工作研究了太阳能系统与燃料电池的结合。实际上，燃料电池是没有任何污染影响的绿色存储系统。它们由氧气和氢气供应以产生电能。这就是为什么无法找到氢源以使用燃料电池的原因。可以采用几种技术来生产氢气，具体取决于资源的可用性和成本。电解池是最常用的技术之一。它们允许通过多种技术从水中获得氢，其中包括在这项工作中考虑的质子交换膜（PEM）。另一方面，电解器需要电力才能运行。可以通过使用可再生能源为燃料电池槽式电解槽供电来构建绿色-绿色能源系统。进行了两个耦合到燃料电池的太阳能系统（光伏和抛物槽）的比较。对黎巴嫩的的黎波里进行了案例研究。该研究显示了两种组合系统在不同参数下的性能，并根据所考虑的配置提出了建议。
