Abstract: A hydrophilic porous polymer film is disclosed that is particularly well-suited for use in an electrolysis cell producing hydrogen. The porous polymer film contains one or more high-density polyethylene polymers in combination with one or more hydrophilic additives. The porous film can be formed through a gel extrusion process or through sintering. Extremely thin films can be produced that have desired permeability characteristics, hydrophilicity characteristics, and mechanical characteristics necessary for use in the cell.

Abstract: A communications hub for a vehicle includes a telematics device including a first communications interface to an external wireless network, a second communications interface to a plurality of vehicle sensors, and a global positioning system (GPS) interface. The telematics device is configured to (i) identify the driver of a vehicle; (ii) retrieve a profile for the driver including a profile permissions log; (iii) establish communications with the wireless network; (iv) establish communications with the vehicle sensor; (v) gather location information from the GPS interface; (v) collect data from a plurality of vehicle sensors; and (vi) send the collected data to an external recipient based on the profile permissions log.
