Designing a Novel Hydrogen Power System for Service Robots

Abstract

Service robots require long operational autonomy and high-power capabilities to perform complex tasks effectively. However, conventional power sources, such as Li-Ion batteries, often fall short in providing extended runtimes, while hydrogen fuel cells, despite their high energy density, exhibit slow dynamic responses. This paper presents a novel hybrid power system that combines a hydrogen fuel cell with a Li-Ion battery pack to power service robots. We introduce a system architecture that dynamically allocates power flow between the fuel cell and the battery, utilizing the battery to meet peak power demands and transient loads, and the fuel cell as the primary energy source for continuous operation. The proposed architecture provides a stable power output under various load conditions, thereby enhancing the capabilities of service robots in diverse operating environments.
