Short Stack type Fuel Cell Evaluation Test Equipment
The equipment is PEFC type short stack evaluation test equipment consisted of gas supply line, moisturizing line, cooling line, cell performance line and safety line.
Mixed gas with optional mixing ratio can be produced by setting total volume and mixing ratio of each gas. Cell is protected by over-flow protection function.
Gas utilizing ratio constant control. Tafel measurement (IV characteristics), Resistance measurement (option)
Stable humidification control, Humidification unit water temperature (+30°C to 90°C), Long term stable operation by humidification unit self-cleaning system, High-speed humidification response (within 3 min - option)
High-speed response cooling system
Resistance measurement at conduction of fuel cell (option)
Various options including pressure test, humidity measurement, etc.
Automatic operation by exclusive control software (CISAS-EX) for controlling of parameters such as gas flow, bubbler temperature, pipe temperature control, load current, etc. for evaluation tests.

Operation control software
Stable software being used in various industrial applications Automatic forwarding of testing items Excellent performance to noise Reduction of CPU load Exclusive software part for fuel cell The software changes process conditions by sequencing numbers of sheets writing test. After judgment of stability, it automatically collect data.
Electronic load unit control
Initial activation automatic operation Load current sweep test=Tafel test
Electronic load (several hundred W to several hundred kW)
As a bias power supply corresponding to 0V, it can be used in a single cell. 3 ranges of current settings, high accuracy of ±0.3% of F.S. For wide frequency from 5mHz to 30kHz For resistance measurement of IR drop, frequency fixed alternative method, frequency sweep alternative method
