Some challenges faced during the fabrication of the proton exchange membrane in fuel cells include high costs incurred from multi-step metal ink production, potential overloading of metal and restricted substrate choices.
The technology comprises of proprietary platinum-based catalyst ink formulations that allows for a simplified process to fabricate proton exchange membrane fuel cells. During membrane production, metal particles can be grown directly on the substrate and cured with low temperature cold plasma (<70°C). This technology can minimize the platinum loading over a wide range of substrates, thereby reducing the cost of producing fuel cell membranes.
Some features of the technology include:
- Thickness range: 30 - 2000nm
- Curing parameters:
- Low temperature (<70°C)
- Fast cure (3-15 minutes)
- No vacuum required except for slight pressure
- Suitable for a wide range of substrates including plastics, paper, fabrics, ceramics, and other metals
- Deposited through methods such as inkjet printing, dip dying and spraying
- No chemical waste, environmentally friendly
- Films formed are solid, highly flexible and durable
Global market size for fuel cells is projected to reach USD 28.95 billion by 2028 with a CAGR of 36.0%. Developed as an alternative energy source, fuel cells are expected to see an increase in adoption in zero emission vehicles due to its superior performance, durability, and efficiency.
