Grant: Idea to Innovation

The convergence of multiple functions in portable electronic devices is resulting in greater power requirements and the incumbent Li-ion battery is becoming limiting. Although existing batteries can accommodate the current power demand, operating time remains a hurdle. The advancement of battery technology is not projected to accommodate the increasing runtime gap. An attractive alternative is the direct methanol fuel cell (DMFC). Liquid methanol is a sustainable electrochemical fuel that has a higher energy density than the Li-ion battery (i.e. more energy per unit volume = longer operation). Additionally, it is easily handled, stored and distributed through existing infrastructure. There is however certain technical barriers, such as fuel crossover, poor kinetics, low efficiency and cost that limit the widespread adoption of conventional DMFCs. The novel membraneless DMFC with simple power control addresses these issues through a simplified system design and has demonstrated significant advantages over the conventional configuration. The objective of the proposed project is to build a prototype battery recharger based on a membraneless DMFC with a simple method of power control. The recharger prototype provides a tangible demonstration of a potential early product incorporating the technology and is a key step in the commercialization pathway of the technology. This will provide significant validation to the technical progress and commercial potential of the technology, and aid immensely in the ability to attract early stage partners and funding for the further development of the technology into a product. It is well-recognized that the clean technology and clean energy sector are key economic opportunities for the future. Canada has a leadership role in the fuel cell sector. The advancement of the novel membraneless architecture will serve to continue the worldwide impact of Canada as a major innovator in the field.
