Title:
ION ANALYSIS DEVICE AND FUEL CELL EVALUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/255446
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fuel cell evaluation system capable of evaluating a condition of a fuel cell that changes moment by moment via ion concentration measurement, with as good response as possible, and capable of reducing, as much as possible, the falling of measurement accuracy due to a condensate being insufficient and the influence on the ion concentration measurement of the amount of the condensate temporarily increasing in fuel cell evaluation in which the ion concentration of discharge water discharged from the fuel cell is measured. This ion analysis device comprises a sampling unit that samples a condensate of discharge gas flowing through a discharge gas flow path of a fuel cell, and a sensor unit that measures the ion concentration of the condensate. The sampling unit either samples the condensate from a first storage part that is formed in the discharge gas flow path and that stores the condensate of the discharge gas, or samples the discharge gas from the discharge gas flow path and stores the condensate of the sampled discharge gas in a second storage part.
