Model TL5 Test Load for Fuel Cells and Batteries |
 The
Model TL5 Test Load for fuel cells and batteries offers several
improvements and enhanced functionality over the earlier TL4
model. It is a passive electronic load with built-in microprocessor
intelligence, with ability to briefly interrupt the current
and take resistance free cell potential readings with programmable
delay. There are additional inputs for a reference electrode
and for a temperature sensor. Microprocessor controls the
time keeping and data acquisition functions, and the measured
values are displayed on an 80-character LCD display. Current
ranges of up to 40 A are operator selectable; voltage (potential)
up to 20.00 V is autoranging. An expansion I/O port with eight
pairs of digital inputs and outputs and two differential analog
inputs allows connection, monitoring and control of additional
sensors.
The instrument has the capability to operate under manual
or remote control, and to communicate with a computer over
a serial RS-485 link. |

| Testmaster™ Fuel Cell and Battery Testing Software |
 Testmaster™
is a powerful, integrated software package designed for testing
of fuel cells and batteries. It runs on a PC computer in a
Windows environment.
It communicates with up to sixteen Model TL5 Test Loads in
a daisy-chain configuration, by means of a single RS-485 serial
port. Testmaster™ performs all the tasks required in
short or long term testing of fuel cells or batteries - monitoring,
control, data collection and storage, and graphical data representation.
Testmaster™ includes all Windows standard user interface
features including multiple document support, dockable toolbars,
tool tips and context sensitive menus, making the application
very user friendly. |

| Quickcell™ QC200 Electrochemical
Test Cell |
 The
Quickcell™ QC200 is an electrochemical test cell designed
for testing of gas diffusion or solid electrodes for fuel cell
and battery research, development and quality control. It is
a quality engineered tool for an electrochemist - scientist,
engineer, student - in pure or applied research, development,
or quality assurance. The cell allows the user to conduct electrochemical
experiments on a small laboratory scale, with closely controlled
parameters. The unit is designed with a relatively large electrolyte
tank with a built in gas lift pump and temperature control element.
A suitable reference electrode can be conveniently inserted
in the electrolyte tank. Two gas chambers provide the gas supply
to the back side of gas diffusion electrodes or allow for circulation
of separate anodic or cathodic working fluid. Electrodes or
membranes are mounted in plastic frames or, for tests of shorter
duration between gaskets that are sandwiched between the cell
body and the gas chambers. The assembly is held together by
nylon bolts. The electrode area is large enough to obtain representative
results of the electrode/process performance, and small enough
so that even delicate electrodes do not require additional support
other than the frame. |

| Model TLIF Interface Module |
 The
Model TLIF Interface Module is a serial communication converter
and power distribution module.
Its first function is to convert serial signals coming from
the computer serial port COM1 or COM2 from the RS-232 protocol
to the RS-485 protocol to allow daisy-chaining of the TL4
or TL5 instruments.
Its second function is to provide power to all the Test Loads
through the daisy-chain connection, eliminating the need for
individual power supplies. |
