Tests on various electric properties ranging from supply of gases to control of humidity and temperature and automatic tracking of equivalent circuits

	Fuel cell analysis system is a comprehensive system aimed to evaluate power generation capability of PEFC and DMFC. The system can comprehensively control software for the purpose of measuring various electric properties ranging from automatic measurement of electric currents and electric potential and analysis on alternating current impedance to measurement of resistance in addition to gas supply, humidification, moisturization, heat, separation of gas from liquid and backing pressure. In addition, measurement of alternating current impedance through the use of FRA automatically analyzes equivalent circuits with high credibility. *The system is configured based on consultation according to specifications.
The system is an evaluator used in conducting element analysis on electrolyte, catalyst, electrode and divider plates and developing fuel cell modules. At a time of development of fuel cells, emphasis was placed on a technology aimed to evaluate properties, but it was developed to analyze power generation characteristics of PEFC or direct methanol fuel cells. The system is a hardware-software package that integrates capabilities of controlling flow of fuel gas, temperature, humidity and pressure and measuring electric properties, which includes an analyzer required to evaluate power generation characteristics of fuel cells and an alternating current impedance gauge. The system can control and measure power generation characteristics of fuel gas simultaneously and consecutively, regulate supply, temperature, humidification and pressure of fuel gas and conduct measurement of properties of electric currents and voltage with regard to a certain rate of fuel use and internal resistance based on a current breaker. In addition, it is possible to conduct automatic testing according to pre-designated sequence. It is also possible to evaluate deterioration of fuel cells, and high measurement accuracy and reenactment have been acquired with regard to measurement of internal resistance. In particular, the company offers accurate measurement of alternating current impedance.

Product overview

Model SERO 2000 (Power Supply & Readout Unit) supplies power to MFC (Mass Flow Controller) and displays stable set-point voltage and flow signal voltage so that the MFC can be accurately controlled. Supplied power is ±15VDC (50W-4Channel), and it is operated as an independent power part in each channel.
It reduces imbalanced voltage occurring at a time of interlocking of MFCs with different capacity and helps minimize interruptions by external power. A precision A/D and D/A converters are built in, and a set-point rate and a measured flow rate are displayed in four digits and seven segments, so it is easy to decipher. In addition, existing variable resistance at a time of calibration was removed, and digital value was stored to keep it from being sensitive to changes in external temperature and realize repeatability and reproduction. In particular, a power switch is placed on a rear panel for the purpose of safety. Since it is programmed as a micro-processor, users can take more diversified approaches to various functions and options based on a wide use.
