Features
- Standalone and
compact equipment
- 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¢XC to 90¢XC), 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.
