Description

technical field

[0001] The invention belongs to the technical field of fuel cells, and specifically proposes a new deflector and a fuel cell stack containing the deflector. Background technique

[0002] A fuel cell is a device that directly converts the chemical energy of hydrogen and oxygen into electrical energy through an electrode reaction. A fuel cell is generally constructed of a plurality of cells, each cell comprising two electrodes (anode and cathode) separated by an electrolyte element and assembled in series with each other to form a fuel cell stack. The electrochemical reaction is achieved by supplying the appropriate reactants to each electrode, ie fuel to one electrode and oxidant to the other, creating a potential difference between the electrodes and thereby generating electrical energy.

[0003] In order to supply each electrode with reactants, specific interface elements commonly referred to as "bipolar plates" and arranged on both sides of each individual...
