Description
|
Multiple individual cells are arranged on a
single electrolytic membrane; a separate
cell is used as pressure sensor. The
membrane is sandwiched between printed
circuit boards wired to achieve series
and/or parallel interconnections.
Photograph of an 8-electrode planar multi-junction
cell. The cell is assembled between two
identical pre-wired current
collectors/compression plates. The
assembled device is 4.5 mm thick and 6.4
cm in diameter.

Advantages
|
Eliminates the complexities of
stacking multiple cells, and the
need for a separate sensor. Improves
reliability, efficiency and
manufacturing cost.
|
|
Applications
|
Planar multi-junction
electrochemical cells can be
used in power generation devices
or in devices converting DC
power into mechanical work.
Applications include:
- Fuel cells (PEM based) mini-power sources.
- Mechanical work generators:
- Electrochemical pumps.
- Electrochemical actuators.
- Electrochemicalcompressors.
