Special Issue Information

Dear colleagues,

Fuel cells are the most efficient and environmentally friendly means of converting chemical energy from hydrogen or hydrogen-rich fuels into electricity. Owing to their modular construction, fuel cells can be built to any size, ranging from a few watts to multiple megawatts. The scalability of fuel cells makes them ideal candidates for a wide range of applications, including portable electronic devices, transportation, and stationary power generation. Some of the obstacles to the quick adoption of fuel cell technology have been the cost and limited availability of hydrogen. However, these obstacles are being gradually overcome with the growing production of hydrogen from renewable energy sources such as solar and wind. The concept of a hydrogen economy, where hydrogen is used as the main energy carrier in various sectors and fuel cells are used to generate clean electricity from hydrogen, is, thus, becoming more realistic. Advancements in fuel cells and in hydrogen production and storage technologies will play key roles in the successful transition to a sustainable hydrogen economy

In this Special Issue, we aim to bring together original research and review articles that describe recent scientific findings, technological breakthroughs, and innovations in the areas of fuel cells and hydrogen energy systems. The topics of interest include, but are not limited to, the following:

  • Advanced materials for fuel cells;
  • Manufacturing processes for fuel cell components and systems;
  • Mobile and stationary applications of fuel cells;
  • Hybrid fuel cell systems;
  • Water electrolysis;
  • Reversible fuel cell–electrolyzer systems;
  • Hydrogen production from renewables;
  • Hydrogen separation;
  • Hydrogen storage and distribution;
  • Hydrocarbon fuels and fuel reforming for fuel cell applications;
  • Hydrogen carriers (ammonia, methanol, etc.);
  • Computational studies for fuel cells and hydrogen energy systems;
  • Process simulations and technoeconomic analyses;
  • Power management and control systems;
  • Hydrogen safety;
  • Policy considerations.

The study examines the effect of using low nickel (Ni) with high ceria (CeO2) anode content towards the oxidation of H2 and CH4 fuel by evaluating the activation energy of the ohmic process and charge transfer process. Using a micro-tubular solid oxide fuel cell (MT-SOFC), the anodes are made up of 50% YSZ with varying NiO:CeO2 percentages from 0% NiO, 50% CeO2 to 50% NiO, 0% CeO2. The performance is measured based on maximum power density (MPD), electrochemical impedance spectroscopy (EIS) and activation energy, Ea of the ohmic (Rohm) and charge transfer (Rct) processes. We found that by lowering the Ni content to lower than 50% NiO, anode conductivity will drop by 7-fold. An anode containing 37.5% NiO, 12.5% CeO2 yield MPD of 41.1 and 2.9 mW cm−2 when tested on H2 and CH4 fuels thus have the lowest Ni content without an abrupt negative effect on the MPD and EIS. The significant effect of conductivity drops on MPD and EIS are observed to occur at 25% NiO, 25% CeO2 and lower NiO content. However, anode content of 25% NiO, 25% CeO2 has the lowest Ea for Rct (29.74 kJ mol−1) for operation in CH4, making it the best anode composition to oxidize CH4. As a conclusion, an anode containing 25% NiO:25% CeO2:50% YSZ and 37.5% NiO:12.5% CeO2:50% YSZ shows promising results in becoming the low Ni anode for coking-tolerant SOFC. Full article
