High Temperature Micro‐Fan for Solid Oxide Fuel Cell Applications

Abstract

The possibility of using a μ‐fan in tubular solid oxide fuel cells module (SOFC‐M) is shown. The μ‐fan is placed instead of the ejector and fulfills its role. The main advantages of this solution are: lower power demanded by the fuel compressor (blower), more stable working characteristics, and the possibility of more accurate control of the recycled part of the anode gas during part load operation. A comparison of two SOFC‐Ms, with and without the ejector, is also shown and commented.

Investigation on High Temperature Corrosion Characteristic of Super304H, TP347H, and HR3C Steel in an Ultra‐supercritical Coal‐fired Boiler▴

“…Usually, to investigate the high temperature corrosion characteristics, coupon testing is conducted [11,12]. Up to now, there are many studies about high temperature corrosion of Super304H, TP347H, and HR3C [13–15].…”

Validated ejector model for hybrid system applications

“…Therefore, the ejector outlet pressure is higher than the value at the secondary inlet, obtaining a significant compression. The main advantages of these machines (in comparison with blowers [4] operating in the same circuit) are: simplicity, low costs and no moving parts. These aspects generate a significant increase in reliability and durability [5].…”
