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)
