Description
Technical Field
The invention relates to the technical field of proton exchange membrane fuel cells, in particular to an anti-reversal additive of a fuel cell membrane electrode and a preparation method thereof, which can effectively relieve carbon corrosion of an anode catalyst layer and agglomeration of platinum particles caused by reversal and improve the durability of a cell.
Background
Proton Exchange Membrane Fuel Cells (PEMFCs) have received extensive attention as a promising candidate for fuel cell electric vehicles due to their zero emissions, high efficiency and high power density. In the past decade, PEMFCs have made significant progress, but there are some obstacles, such as low durability, high cost, and infrastructure insufficiency, which must be solved before they are widely commercialized.
When a fuel cell vehicle is operated under complex operating conditions, fuel starvation conditions, such as rapid load changes and a sub-zero start, are typically present. When the anode fuel is insufficient, hydrogen is no longer sufficient to provide the necessary protons and electrons, and therefore the water electrolysis reaction and carbon corrosion will occur separately, the anode developing a high potential, causing the cell voltage to reverse, i.e., reverse polarity. Carbon corrosion consumes the carbon support, destroys the catalyst layer structure, and causes platinum particles to agglomerate, thereby causing degradation in cell performance. In severe cases, the large amount of heat generated by the high potential of the anode can cause pinholes in the pem and fuel and oxidant mixing inside the cell, causing catastrophic failure.
To date, researchers have developed various system control strategies to prevent cell voltage reversal, such as monitoring cell voltage, detecting CO in tail gas2Concentration and monitoring of reactant gas stoichiometry, etc. These system strategies all require additional system support, increasing the cost and complexity of the stack. Yet another material-based strategy solves this problem, which is mainly to add an electrolyzed water catalyst such as iridium and its oxide, ruthenium and its oxide, iridium-ruthenium alloy, etc. in the anode catalytic layer. But the expensive cost and limited inventory of precious metals also limits their use as individual catalyst additives.
CN111029599A discloses a fuel cell anti-reversal catalyst and a preparation method thereof, wherein the catalyst is an iridium oxide and niobium composite doped titanium dioxide nano catalyst, and the adoption of the invention can effectively relieve carbon carrier corrosion and platinum particle agglomeration growth during reversal of the anode side of the fuel cell, so that the fuel cell anti-reversal time is prolonged. However, the preparation process of the catalyst is complicated and requires high-temperature hydrogen reduction. And the conductivity of the titanium oxide is poor, and obvious mass transfer polarization can occur under high electric density after the catalyst is added into the anode catalyst layer.
