Fuel Cell, Systems and Technologies

The influences of various test conditions on the electrochemical performances are shown below. The electrochemical performances are presented as polarisation curves ( cell voltage as a function of current density) obtained under the following test conditions:

1. Influence of gas pressure : with hydrogen and oxygen.
2. Influence of cell temperature : with hydrogen and oxygen.
3. Infulence of gas pressure : with dry hydrogen and 100% humidified air.
4. Influence of cell temperature : with dry hydrogen and 100% humidified air.
5. Influence of air humidification : with dry hydrogen and low % relative humidity air.

1) Influence of gas pressure : with hydrogen and oxygen.

2) Influence of cell temperature : with hydrogen and oxygen.

3) Influence of gas pressure : with hydrogen and 100% humidified air.

4) Influence of cell temperature : with hydrogen and 100% humidified air.

5) Influence of air humidification : with dry hydrogen and low % relative humidity air.
