Bipolar plate for the conversion of the electrical energy to chemical energy of hydrogen (anode side).

In the F3 time period, we have manufactured the prototypes of bipolar plates for the conversion of electrical energy to the chemical energy of hydrogen (Fig. 1) and the bipolar plates for the conversion of the chemical energy of hydrogen to the electrical energy of hydrogen (Fig. 2). We have tested the bipolar plate in an appropriate electrode system. Figure 3 provides the results of PEM water electrolysis in the generation of hydrogen at different temperatures and the exergetic effect at different flows of generated hydrogen (Fig. 3).
