Anion-Exchange Membrane Water Electrolyzers for Green Hydrogen Generation: Advancement and Challenges for Industrial Application

ACS Applied Energy Materials, Год журнала: 2024, Номер unknown

Опубликована: Авг. 30, 2024

Hydrogen is emerging as a strong contender for feasible future energy carrier in the clean race, due to its high density and burning nature. However, account environmental challenges, production must be sustainable cost-efficient. Currently, hydrogen generated from various feedstocks such ammonia, methane, natural gas, biomass, smaller organic molecules, water. These undergo different catalytic processes, including decomposition, electrolysis, steam reforming, pyrolysis, gasification, photoassisted methods photoelectrochemical, biophotolysis, photocatalysis, etc. Among all, research on water electrolysis has garnered much attention because of their carbon free green with use electrolyzers (WEs). On basis recent reports International Renewable Energy Agency (IREA), major types used industry are alkaline (AWE), proton-exchange membrane (PEMWEs), anion-exchange electrolyzer (AEMWE). them, AWEs PEMWEs have inherent drawbacks which need attention. AEMWEs can considered promising alternative by integrating advantages both into one device. In this review, we focused core ideas AEMWEs, where scientific engineering breakthroughs highlighted. It points out importance eliminating gap between electrodes (i.e., zero concept) identifies areas that further development push AEMWE technology forward. offer higher operating current densities pressures, comparable Faradaic efficiencies (>90%), utilization nonprecious metal catalysts along pure feed. Along all these, also advancements deterioration AEMs. Additionally, it provides concise overview performance offers detailed examination developments electrolyte feeding group (non-PGM) electrocatalysts.

Ether‐Free Alkaline Polyelectrolytes for Water Electrolyzers: Recent Advances and Perspectives

Angewandte Chemie International Edition, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 1, 2024

Anion exchange membrane (AEM) water electrolyzers (AEMWEs) have attracted great interest for their potential as sustainable, environmentally friendly, low-cost sources of renewable energy. Alkaline polyelectrolytes play a crucial role in AEMWEs, determining performance and longevity. Because heteroatom-containing polymers been shown to poor durability alkaline conditions, this review focuses on ether-free polyelectrolytes, which are more chemically stable. The merits, weaknesses, challenges preparing AEMs summarized highlighted. evaluation synthesis methods polymers, modification strategies, cationic stability will provide insights valuable the structural design future polyelectrolytes. Moreover, situ degradation mechanisms ionomers during AEMWE operation revealed. This provides into AEMWEs accelerate widespread commercialization.
