Abstract: The valve comprises a movable closure member and a seat in which the closure member is displaced relative to the seat for varying the gas flow through the valve. According to the invention, the process comprises causing the displacement of the movable closure member by means of a step-by-step motor as a function of the variation of the flow produced by each step according to the geometry of the valve, the type of flow employed and the pressure of the gas on the upstream and/or downstream side of the valve, and then producing a corresponding control signal for displacing in the desired direction the motor through the number of steps corresponding to the calculated flow, the displacement of the motor causing the correlative displacement of the movable closure member.

Title: Solid polymer electrolyte fuel cell system with  porous plate evaporative cooling
Inventor: KUNZ HAROLD R
IPC: H01M8/10
Filed: 1989-02-10
Granted: 1992-10-20
Abstract: Abstract Solid Polymer Electrolyte Fuel Cell System With Porous Plate Evaporative Cooling A fuel cell or fuel cell stack of the type utilizing a solid polymer electrolyte membrane is cooled by evaporation of water in the hydrogen reactant chamber of the cells.  A porous graphite plate or water permeated membrane is disposed in the hydrogen reactant chamber adjacent to the electrolyte membrane.  If a graphite plate is used, it is preferably grooved on the surface facing the electrolyte.  The resultant lands preferably contact the supported catalyst layer on the membrane to cool the latter.
