摘要：

A comprehensive mathematical model for the hydrogen storage system is derived in order to get a closer insight into total system efficiency and different loss mechanisms. The hydrogen production, storage and conversion sub-systems are studied in detail and respective models with illustrative case examples are presented. The hydrogen balance of the pressurised hydrogen-storage vessel is described by a first-order differential equation, while the electrochemical performance of the electrolyser and the fuel cell are described by the voltage and current efficiencies. The overall performance of the hydrogen production and conversion sub-systems is described by production and conversion efficiencies which also consider parasitic losses. The electrochemical characteristics are the most significant factors influencing total system efficiency, but parasitic losses, such as the power consumption of the process control and gas handling system, or hydrogen gas losses, may also play a significant role in small-scale applications.
