Catalyst Loading | Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
Membrane electrode assembly types | 3-layer, 5-layer, 7-layer (so before ordering, please clarify how many layers MEA you prefer, and also provide the MEA drawing). |
The function of fuel cell MEA:
-Separating reactants: prevents direct contact between hydrogen and oxygen.
-Conducting protons: allows protons (H+) to pass from the anode through the membrane to the cathode.
-Catalyzing reactions: Promotes hydrogen oxidation at the anode and oxygen reduction at the cathode.
-Generating current: produces electron flow through electrochemical reactions.
-Managing water: maintains proper water balance to ensure continuous reactions.
VET Energy has independently developed high-performance MEAs, through advanced catalysts and MEA production processes, it can have:
current density: 2400mA/cm2@0.6V.
power density: 1440mW/ cm2@0.6V.
The main structure of fuel cell MEA:
a) Proton Exchange Membrane (PEM): a special polymer membrane in the center.
b) Catalyst Layers: on both sides of the membrane, usually composed of precious metal catalysts.
c) Gas Diffusion Layers (GDL): on the outer sides of the catalyst layers, typically made of fiber materials.
