Context

The growing demand for clean energy implies a strong challenge on decarbonised energy sources among which hydrogen is showing strong growth. The Amylion project proposes a component compatible with environmental goals of green energy and electrochemistry.

Technology

In the field of bioelectronics based on bio-materials, a new proton exchange membrane has been designed and developed by the research labs using green chemistry methods. It is a biocompatible and biodegradable protein material transforming co-products from the food and beverage industry.

Advantages

• Abundant bio-sourced and biodegradable material

• Valorisation of a co-product

• Low cost (<10% of the cost of comparable petro-sourced products)

• Green chemistry manufacturing

• Very good performance at low temperature and low humidity

State of progress

A first demonstrator has been developed and tested in the research lab (TRL 4). Its main characteristics have been validated, notably its stability up to 60°C and its durability over time (10 hours of continuous operation). The proton exchange functionality has been demonstrated on a surface of several cm2.

Applications

Energy and electrochemistry

  • Fuel cells
  • Redox flow batteries
  • Electro-dialysis
  • Electrochemical sensors
  • Hygrometric control
  • Chemical processes (Cl2 production, NaOH)
