TL;DR
This paper reviews how hydrogen peroxide harms proton exchange membrane technologies and explores ways to detect and mitigate its effects.
Contribution
The paper provides a systematic review of hydrogen peroxide's formation, detection, and mitigation in PEMFCs and PEMWEs.
Findings
Hydrogen peroxide degrades PEM components through reactive radicals, reducing device efficiency and lifespan.
Current detection methods for hydrogen peroxide are inadequate under real operating conditions.
Emerging catalytic strategies aim to suppress hydrogen peroxide-induced damage in PEM technologies.
Abstract
Hydrogen peroxide is a catalytic byproduct in proton exchange membrane fuel cells (PEMFCs) and proton exchange membrane water electrolyzers (PEMWEs). It may be produced as a side product of the electrochemical processes occurring at the cathode in PEMFCs, or at the anode in PEMWEs, or it may be produced due to gas crossover through either catalytic chemical or electrocatalytic processes. The challenge posed by H2O2 is its catalytic decomposition into highly reactive hydroxyl and peroxyl radicals, which trigger cascading degradation of critical components. This degradation directly compromises device efficiency and shortens the lifespan, representing a limiting factor in the durability of PEMFCs and PEMWEs. However, existing methods for detecting and quantifying in situ H2O2 generation are limited in their ability to accurately reflect real operating conditions (e.g., high current…
