1. A process for pressure bonding a consumable, reactive metal anode plate to a bipolar plate for use in an electrochemical cell, comprising the steps of:
- applying pressure by means of a constant force press to the anode plate in a first area to mechanically bond that area of the anode plate to the bipolar plate; and
applying pressure seriatim by said press to other areas of the anode plate leading away from said first area to progressively mechanically bond those areas of the anode plate to the bipolar plate, thereby forcing out any trapped air from between the plates.

Abstract
A process for pressure bonding a consumable, reactive metal anode plate to a bipolar plate for use in an electrochemical cell. Pressure is applied to the anode plate in a given direction progressively over a given area to mechanically bond that area of the anode plate to the bipolar plate, thereby forcing out any trapped air from in between the plates.

8. A process for pressure bonding a consumable, reactive metal anode plate to a bipolar plate for use in an electrochemical cell, comprising the steps of:
-
applying pressure to the anode plate in a first area at a location generally centrally of the anode plate to mechanically bond that area of the anode plate to the bipolar plate; and applying pressure seriatim to other areas of the anode plate at locations radiating outwardly of the central area to progressively mechanically bond those areas of the anode plate to the bipolar plate, thereby forcing out any trapped air from between the plates. - View Dependent Claims (9, 10)

- 11. A process for pressure bonding a consumable, reactive metal anode plate to a bipolar plate for use in an electrochemical cell by applying pressure by means of a constant force press to the anode plate sequentially over a plurality of discrete planar areas to mechanically bond the areas to the bipolar plate and to force out any trapped air from between the plates.

16. A process for pressure bonding an anode plate to a bipolar plate for use in an electrochemical cell, comprising the steps of:
-
providing a consumable, reactive metal anode plate; providing a metallic bipolar plate; placing said plates in juxtaposition; applying pressure to a first area of the anode plate at a generally central location to mechanically bond that area of the anode plate to the bipolar plate; and applying pressure seriatim to a series of radial areas of the anode plate leading outwardly away from said first area to progressively mechanically bond the radial areas of the anode plate to the bipolar plate, thereby forcing out any trapped air from between the plates. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A process for pressure bonding a consumable, reactive metal anode plate to a bipolar plate for use in an electrochemical cell by applying pressure to the anode plate progressively over a given area in a direction radially outwardly from a generally central location of the anode plate to mechanically bond that area of the anode plate to the bipolar plate and to force out any trapped air from between the plates.
