What is a bipolar plate in a proton exchange membrane fuel cell?

Bipolar plates are a crucial component of proton exchange membrane fuel cells. They are responsible for transporting reactant gases, carrying the current from the membrane electrode assembly to the end plates, providing heat and water management, and separating the individual cells.

What is stainless steel bipolar plate?

stainless steel bipolar plates need further research. Fabricating methods of the metal bipolar plate are presented. Bipolar plate is one of the most significant components of the proton exchange membrane fuel cell, which serves as the function of reactant gases supply, reaction products removal, current collection, structural support and so on.

What is a bipolar plate in A PEMFC?

Bipolar plate, also called the current collecting plate, is one of the most crucial elements of the PEMFC. The primary function of the bipolar plate is to supply a gas flow channel, prevent hydrogen and oxygen in the fuel cell from colluding, and establish a current path between the anode and cathode in series.

How important are bipolar plates in proton PEMFC?

Bipolar plates are account for exceeding 60 % of volume and 30 % of the overall expenses in the PEMFC stack, which has a significant influence on the large-scale commercial application of proton PEMFC .

Why is metal bipolar plate coated with conductive protective film?

In order to meet the long-term test requirements of commercial application, the metal bipolar plate must be coated with conductive protective film to avoid the degradation of performance fuel cell in long-term operation. 5.1.2.

Are bipolar plates a reversible hydrogen electrode?

The researchers investigate bipolar plates made from a thermoplastic-bound carbon matrix. The team test them in an ex situ corrosion cell under various conditions thought to simulate typical electrolyser environments: temperatures of 40–80 °C; pH values between 0 and 4; and potential of 2 V versus RHE (reversible hydrogen electrode).
