Power electronics and fuel cell technologies play an important role in the field of renewable energy. The demand for fuel cells will increase as fuel cells become the main power source for portable applications. In this application, a high-efficiency converter is an essential requirement and a key parameter of the overall system. This is because the size, cost, efficiency, and reliability of the overall system for portable applications primarily depend on the converter. Therefore, the selection of an appropriate converter topology is an important and fundamental aspect of designing a fuel cell system for portable applications as the converter alone plays a major role in determining the overall performance of the system. This paper presents a review of power electronics applications in fuel cell systems, which include various topology combinations of DC converters and AC inverters and which are primarily used in fuel cell systems for portable or stand-alone applications. This paper also reviews the switching techniques used in power conditioning for fuel cell systems. Finally, this paper addresses the current problem encountered with DC converters and AC inverter.
电力电子技术和燃料电池技术在可再生能源领域发挥着重要作用。随着燃料电池成为便携式应用的主要电源，对燃料电池的需求将会增加。在这种应用中，高效转换器是一项基本要求，也是整个系统的关键参数。这是因为便携式应用的整个系统的尺寸、成本、效率和可靠性主要取决于转换器。因此，选择合适的转换器拓扑结构是设计用于便携式应用的燃料电池系统的一个重要且基本的方面，因为仅转换器就在决定系统的整体性能方面起着主要作用。本文综述了电力电子技术在燃料电池系统中的应用，其中包括直流转换器和交流逆变器的各种拓扑组合，这些组合主要用于便携式或独立应用的燃料电池系统。本文还综述了燃料电池系统功率调节中使用的开关技术。最后，本文讨论了直流转换器和交流逆变器目前遇到的问题。
