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.

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°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.
