Fundamental technologies

The fundamental technologies are linked to the electrochemical cores and the processes taking place. There are H2/O2 and H2/air type PEM fuel cell technologies, as well as PEM electrolysis technology.

  PEM (PROTON EXCHANGE MEMBRANE) FUEL CELLS

HELION devotes a large part of its R&D in the area of PEM fuel cell technologies in collaboration with its partners. Development covers the improving of the following key points:

  • the performance of key components in both stack and system
  • the operating and ageing mechanisms

The objective aimed for is a perfect mastery of the technologies, large reductions in weight and volume, an increase in the durability of systems and significant reduction of costs.

  H2/OTECHNOLOGY

Principle:

  • The stack is supplied with pure hydrogen and oxygen

Advantages:

  • Simple and reliable system
  • High durability
  • Complete autonomy in relation to the exterior
  • High system yield
  • Silent operation

Target applications:

  • Backup power systems offering high availability and reliability
  • Applications in extreme milieu
  • Marine and submarine applications 
  • Stabilisation of electrical grids
  H2/AIR TECHNOLOGY

Principle:

  • The stack is supplied with pure hydrogen and with air

Advantages:

  • No pure oxygen logistics, but an intake of air

Target applications:

  • Transport in an aerobic milieu
  • Portable generator units


Over the last 4 years, stacks have seen their costs reduced by a factor of 4 to 5 while their power has increased by a factor of 10, rising from 5 kWe in 2003 to more than 60 kWe at present.

  DEVELOPMENT IN PERFORMANCE

  PEM ELECTROLYSIS

HELION develops PEM technology electrolysers for decentralised hydrogen production.

This technology, which complements that used in fuel cells, has numerous advantages:

  • Clean production of hydrogen and oxygen from water
  • Purity of gas produced (no chemical contaminants)
  • Complements PEMFC technology
  • Operating pressure compatible with target applications
  TECHNOLOGICAL FORECASTS

This technology is undergoing heavy R&D investment both internally and with our partners. This focus is on:

  • Cost reduction of the hydrogen produced
  • Production range from 10 to 100 Nm3/h
  • Optimising of the operating pressure depending on the application
  • Use of new less expensive catalytic materials
  • New materials and processes for inter connectors
  • Increases in performance
  • Industrialisation of manufacturing process
  HIGH TEMPERATURE ELECTROLYSIS

In parallel to these developments, HELION devotes a large part of research and development to high temperature electrolysis technology.
