DescriptionItem ref. P103
Field of use: general science and chemistry, FC engineering
Education grades: 7th – 12th, university/college, vocational training
Package suitable for a low and high level of engineering training on fuel cells and fuel cell systems with hands-on experimentation. The included ClearPak fuel cell delivers high current densities with a realistic thermal response. Water management inside the cell is clearly visible. Pack enables the control of fuel cell performances through the complete balance-of-plant system. Also possible to perform temperature-dependent and time-dependent testing as well as compare efficiencies of various system configurations.
Key features - High performance, large fuel cell
