A highly-robust solid oxide fuel cell (SOFC): simultaneous greenhouse gas treatment and clean energy generation

Abstract

Herein, results of combined greenhouse gas treatment with clean energy conversion is reported for the first time. Multi-channel tubular SOFCs were operated with N 2 O instead of air as the oxidant leading to a 50% increase in power density. Techno-economic evaluation suggested the feasibility of the combined approach eliminating the cost penalty for N 2 O abatement.

Rare earth elements based oxide ion conductors

“…Therefore, SOFCs have become a sustainable energy technology for the future, owing to several critical advantages such as high overall energy efficiency (up to 80%), fuel flexibility, and relatively low catalyst cost. [13][14][15][16] As shown in Fig. 1, a SOFC consists of three main components, namely, an oxygen electrode, a fuel electrode, and a dense electrolyte.…”

A Comprehensive Review on the Recent Development of Ammonia as a Renewable Energy Carrier

“…In addition, there was no evidence of ammonia having a bad effect on the ceramic electrolytes used in SOFCs [190]. Nonetheless, because of the fragility of porcelain materials, SOFCs are usually not appropriate for transport use [191].…”

A carbon dot‐based total green and self‐recoverable solid‐state electrochemical cell fully utilizing O2/H2O redox couple

“…The consumption of nonrenewable fossil fuels and emissions of greenhouse gases such as carbon dioxide have led to serious global problems, such as environmental pollution, climate change, etc 1–4 . The environmental concerns have stimulated the great attentions in generating the electricity from clean energy sources, for example, solar, wind, etc, which provide efficient and environmentally preferable alternatives to minimize the environmental impacts 5–8 .…”
