The Hardware :
Electrolysis performance evaluation tool (EPET) V 5 - system brings together disparate devices into a unified harmony
Precision Power Delivery: At the core of the setup are Thurlby Thandar Instruments (TTi) CPX400 series DC Power Supplies, specifically the CPX400DP (Dual 420-watt) and CPX400SP models
.
Fluid Management: Electrolyte flow is meticulously managed by a REGLO digital peristaltic pump
. Through the LabVIEW interface, the pump can be controlled either by direct rotor speed or by specifying the exact flow rate .
Driverless Thermal Monitoring: Temperature tracking is handled by Yoctopuce dual driverless thermocouple sensors, delivering precise thermal data directly to the central dashboard
.
Automated Relay Control: For auxiliary controls, the system employs a Denkovi Assembly Electronics 4-channel USB relay board to safely switch heaters on and off
.
EPET 5.0 Software Interface
Built on LabVIEW 15 (RTE required), the EPET 5.0 dashboard is designed with the researcher in mind, prioritizing safety and real-time visualization
Advanced Safety Limits: Researchers can establish strict voltage safety limits, which is highly useful when conducting constant current tests
. Automated Cycling: The software supports multiple repeats and cycles of current or voltage sweeps
. Real-time Visualization: As data is captured, EPET 5.0 generates real-time visualizations of polarization curves
. Integrated Controls: The UI includes built-in controls for the Yoctopuce temperature probes and the Denkovi heater relay switches
.
Data Extraction and Processing
Collecting data is only half the battle. Accompanying EPET 5.0 is a specialized data extraction tool. This post-processing utility is engineered to handle original, edge, and stepped data for voltage and current density, allowing users to easily parse and analyze the results of their sweeps
