“…Maximum mass flow rate from outlet 3 reaches 0.37 kg/s. The mass flow rate of a centrifugal compressor designed by Qi et al 15 was in the range of 0.022–0.068 kg/s, additionally, the compressor efficiency increased with rotation speeds. It has a similar size to the authors’ ORP compressor.…”

“…Small-scale centrifugal compressors have been widely investigated because of their applications in turbocharged systems; however, the requirements of air compressors in PEM fuel cell systems are different from those in turbocharger systems. Qi et al 15 designed and researched a centrifugal compressor for an air supply system. The maximum efficiency and pressure ratio of this compressor were 83% and 2.2, respectively.…”

Automotive polymer electrolyte membrane fuel cell systems are attracting much attention, driven by the requirements of low automotive exhaust emissions and energy consumption. A polymer electrolyte membrane fuel cell system provides opportunities for the developments in different types of air compressors. This paper proposed an opposed rotary piston compressor, which had the merits of more compact structures, less movement components, and a high pressure ratio, meeting the requirements of polymer electrolyte membrane fuel cell systems. Preliminary performance evaluations of the opposed rotary piston compressor were conducted under various scenarios. This will make a foundation for optimizations of outlet pipe layouts of the compressor. A three-dimensional numerical simulation approach was used; further, in-cylinder pressure evolutions, fluid mass flow rates, and P – V diagrams were analyzed. It indicated that the cyclic period of the opposed rotary piston compressor was half of reciprocating piston compressors. The specific mass flow rate of the compressor is in the range of 0.094–0.113 kg·(s·L) −1 for the given scenarios. Outlet ports 1 and 2 dominated the mass flow in the discharge process under scenarios 1, 3, and 4. In-cylinder pressure profiles show multipeaks for all of these scenarios. In-cylinder pressure increased rapidly in the compression process and part of the discharge process, which led to high energy consumption and low adiabatic efficiency. The maximum adiabatic efficiency is approximately 43.96% among the given scenarios.
