Abstract
An electrochemical cell in the form of first and second sheet members (2,12) at least one of which is gas permeable on which is disposed one or more planar electrodes (4,6,8). Peripheral regions of the first and second sheet members (2,12) are sealed together to form a sealed envelope or reservoir containing electrolyte. Electrical connection means (41,61,81) extend from each of the electrodes (4,6,8) across the sealing of the sheet members (2,12) to provide external electrical connection.
Claims25
A gas sensor consisting of an electrochemical cell, comprising:
- a first sheet member having thereon a gas permeable section, said gas permeable section having disposed thereon a plurality of planar electrodes;
- a second sheet member,
- wherein peripheral regions of said first sheet member and said second sheet member being sealed together to form a reservoir therebetween, said reservoir being adapted to contain electrolyte;
- and
- electrical connection means extending from each of said plurality of planar electrodes to said peripheral regions of said first sheet member and said second sheet member, said electrical connection means being adapted to provide a respective external electrical connections for said plurality of planar electrodes.
A gas sensor consisting of an electrochemical cell assembly, comprising:
- a plurality of sections;
- and
- manifold means,
- wherein each of said plurality of sections comprises:
- a first sheet member;
- and
- a second sheet member,
- wherein each of said first sheet member and said second sheet member has a gas permeable region on which at least one planar electrode is disposed, peripheral regions of said first sheet member and said second sheet member being sealed together to form a reservoir therebetween adapted to contain electrolyte,
- wherein each of said plurality of sections has electrical connection means extending from said at least one planar electrode across said sealed together peripheral regions of said first sheet member and said second sheet member, said electrical connection means providing external electrical connection, and
- wherein said manifold means directs a first gas and a second gas to each of said plurality of sections, said first gas being directed to contact one of said first sheet member of respective one of said plurality of sections, and said second gas being directed to contact said second sheet member of said respective one of said plurality of sections.
