Nanoporous Silicate Membranes for Portable Fuel Cells


Description of Technology:

The technology disclosed is a fuel cell which has a significantly reduced internal resistance that can also be miniaturized. Two substrates are prepared, on with microchannels running along its facing surface and the other with nanochannels running along its facing surface. A silica-based binder is used to bind the substrates together with the microchannels running orthogonal to the nanochannels. The binder is removed from the microchannels and a fuel is introduced into at least one of the microchannels and an oxidant is introduced into at least one of the other microchannels.


The fuel cell can have a large impact by running low power devices in remote locations, including spacecraft, remote weather stations, large parks, rural locations and certain military applications.

Features and Benefits:

This fuel cell, which requires no flow, may reduce the cost involved in producing portable fuel cells while increasing usage over a wider range of applications. Larger power outputs may also be possible through integration of multiple fuel cells in series on a single footprint, creating a high energy portable power source for the future.
