The survey of key technologies in hydrogen energy storage

Electrocatalysis plays a central role in clean energy conversion, enabling a number of processes for future sustainable technologies. Atomic site electrocatalysts (ASCs), including single-atomic site catalysts (SASCs) and diatomic site catalysis (DASCs), are being pursued as economical alternatives to noble-metal-based catalysts for these reactions by virtue of their exceptionally high atom utilization efficiencies, well-defined active sites and high selectivities. In this review, we start from a systematic review on the fabrication routes of ASCs followed by an overview of some new and effective characterization methods to precisely probe the atomic structure. Then we give a comprehensive summary on the current advances in some typical clean energy reactions: water splitting, including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER); oxygen reduction reaction (ORR), including selective 4e- - ORR toward H2O/OH- and 2e- - ORR toward H2O2/HO2-; selective electrooxidation of formic acid, methanol and ethanol (FAOR, MOR and EOR). At the end of this paper, we present a brief conclusion, and discuss the challenges and opportunities on the further development of more selective, active, stable and less expensive ASCs.

Critical challenges in the system development of direct alcohol fuel cells as portable power supplies: An overview

Hydrogen (H 2 ) gas is a clean energy carrier and has high energy density. Currently, most H 2 gas is produced by carbon-based non-renewable sources, such as natural gases, coal, heavy oil and naptha, as well as from the electrolysis of water. However, the production of H 2 from fossil fuels generates greenhouse gases and requires high energy. Thus, it is important to develop alternative H 2 production routes that are renewable, such as biohydrogen. This paper focuses on reviewing and discussing biohydrogen production technologies, including the mechanism and bioreactor system, and the biohydrogen purification system using membrane technology in the application of the polymer electrolyte membrane fuel cell (PEMFC). In addition, the sizes of bioreactor required to generate H 2 to power the PEMFC stack are calculated and compared in order to determine the potential application of hydrogen production through the biological pathway.
