Fuel Cells

De Nora focuses its attention on
High-Temperature PEM fuel cell, Phosphoric Acid fuel cell, Direct Methanol fuel cell, and Alkaline fuel cell.

High Performance

Flexibility

Energy Saving

Depending on the quality of the power mix, electricity can be converted into potentially green hydrogen by electrolysis.

The hydrogen can be then stored and eventually re-electrified.
The overall round-trip efficiency of this process, often identified as “Power to Power” route, is currently lower than other storage technologies.

Despite this low efficiency, the interest in hydrogen energy storage and eventually its reconversion to power, is growing, due to the much higher storage capacity compared to batteries (small scale) or pumped hydro and CAES (large scale).
Hydrogen can be re-electrified in fuel cells with efficiencies up to 50% or even higher when a combinad heat and power (CHP) set up could be used.

Fuel cells convert chemical energy directly into electrical energy by the reverse process to that of electrolysis: hydrogen gas reacts with oxygen to produce water and an electrical current. Unlike combustion in gas turbines, electrochemical reactions produce electricity directly and do not require any moving parts, which makes fuel cells more reliable.

Similar to electrolyzer cells, fuel cells are highly modular and can supply a broad range of power applications, from small portable equipment to megawatt bulk generation.

Between the different types of fuel cells, De Nora is focusing its attention on:

  • high-temperature PEM fuel cell,
  • phosphoric acid fuel cell,
  • direct methanol fuel cell
  • alkaline fuel cell.

For each of these technologies, De Nora could provide anode and cathode catalysts, gas diffusion electrodes (GDE), Gas Diffusion Layers (GDL), Membrane Electrodes Assembly (MEA), various types of flow fields, and other cell components.
