Title: Heel and toe driving on fuel cell vehicle

Abstract

A system and method for providing nearly instantaneous power in a fuel cell vehicle. The method includes monitoring the brake pedal angle and the accelerator pedal angle of the vehicle, and if the vehicle driver is pressing both the brake pedal and the accelerator pedal at the same time and the vehicle is in a drive gear, activating a heel and toe mode. When the heel and toe mode is activated, the speed of a cathode compressor is increased to a predetermined speed set-point, which is higher than the normal compressor speed for the pedal position. Thus, when the vehicle brake is removed, the compressor speed is high enough to provide enough air to the cathode, so that the stack can generate nearly immediate power.

  • A matrix for retaining the electrolyte in a fuel cell is applied to the surface of one or both of the electrodes by screen printing using an inking vehicle which is an aqueous solution of polyethylene oxide. This method produces a very thin, continuous and uniform matrix layer and is well suited to production operations. 4 claims, 1 figure.
  • This patent describes a camshaft drive for an internal combustion engine comprising at least one cylinder, first and second camshafts supported for rotation about parallel and offset axes, an output shaft, and first timing drive means for driving the first camshaft directly from the output shaft on one side of the one cylinder. It also has a second timing drive means for driving the second camshaft from the first camshaft on the other side of the one cylinder.
  • A control device is described for driving road-vehicle electric-powered equipment comprising: a supporting means for supporting the equipment in a movable manner; an electric-powered driving mechanism for driving the equipment; an electric driver for actuating an electric motor in the electric-powered driving mechanism; a switch means for instructing driving of the electric-powered driving mechanism; and an electronic control device for reading a time-serial signal pattern generated in accordance with plural successive opening/closing operations of the switch means, and for actuating and controlling the electric motor in accordance with the opening/closing pattern.
