US 6,649,294 B2 · Metal-air fuel cell battery systems having mechanism for extending the path length of metal-fuel tape during discharging and recharging modes of operation

Abstract

Disclosed is a method and apparatus for extending path-length of metal-fuel tape during discharging and/or recharging operations so that a supply of metal-fuel tape contained within a cassette device or on a supply reel can be rapidly discharged and/or recharged in an improved manner. During discharging operations, a plurality of discharging heads are selectively arranged about the extended path-length of metal-fuel tape so as increase the rate at which electrical power is powered from the system. During recharging operations, a plurality of recharging heads are selectively arranged about the extended path-length of metal-fuel tape to decrease the time required to recharge the metal-fuel tape transported through the system.

Dependent claims

A metal air fuel cell battery system comprising:

a Metal-Fuel Tape Discharging Subsystem;
a Metal-Fuel Tape Recharging Subsystem integrated with the Metal-Fuel Tape Discharging Subsystem;
and
a tape path-length extension mechanism employed in said Metal-Fuel Tape Recharging Subsystem for extending oxidized metal-fuel tape from a first position to a second position over a path length which is greater than the path-length maintained by the tape-length the extension mechanism in said Metal Fuel Tape Discharging Subsystem such that a recharge surface area is greater than a discharge surface area.

1 more element

A metal air fuel cell battery system comprising:

means for discharging and recharging metal-fuel tape in a single hybrid subsystem, wherein a tape path-length extension mechanism is employed therein for extending metal-fuel tape from a first position to a second position to be recharged over a path which is greater than the path maintained for metal-fuel tape to be discharged.

Dependencies are inferred from the claim text.
