Monitoring assembly for use in a fuel-cell system - Patent Abstract

Applicant: Fuelcell Energy Inc, USA

A monitoring assembly for use in a fuel-cell system for detecting sulphur-containing compounds in the fuel has been developed. The monitoring assembly consists of an indicator unit through which fuel passes. This unit includes an indicator material and a housing to protect this material. The housing is adapted to be placed on-line in the main path that receives substantially all of the fuel and a bypass path which receives only a portion of the fuel in the fuel-cell system. When the housing is placed on-line, at least one physical property of the indicator material changes when it is exposed to sulphur-containing compounds in the fuel. The indicator unit is also designed to detect the change in the physical property of the indicator material.
