A 50 kW PEMFC Pilot Plant Operated with Industry Grade Hydrogen – System Design and Site Integration

Abstract

The chlor‐alkali industry produces high amounts of hydrogen as a by‐product of processes based on electrolytic cells. In order to improve the process' efficiency, plant operators seek ways to utilize this potential and fuel cells offer a sensible solution, producing electricity at high efficiency. PEMFC has already been demonstrated to be successful in this niche market application with a few commercial scale installations. In the DuraDemo project, a 50 kW stationary PEMFC pilot plant has been designed in a publicly funded national project involving partners from different parts of the value chain. The plant serves as an experimental platform for evaluation of BoP and power electronics components, as well as hydrogen quality studies. The system design is targeted to be commercially viable and a large amount of extra instrumentation and experimental monitoring equipment are utilized in the pilot plant to analyze its behavior. The pilot plant is fully automated and capable of independent operation with remote monitoring and data logging capability. The system design of the pilot plant is presented, including BoP component selection and characterization of the main components. Final assembly testing results, integration of the plant at its demonstration site and safety analysis work will be reported.

Remodeling of a commercial plug-in battery electric vehicle to a hybrid configuration with a PEM fuel cell

“…The commercial refueling WEH  system is formed by the TK-16 nozzle and the TN-1 receptacle, and integrates a high-flow check valve and a self-cleaning particle filter (20 micron). or hydrogen purge strategies [18][19][20][21][22][23][24]. To this end, hydrogen blowers, recirculation pumps or Ventury-type ejectors are included at the anode gas line.…”

Control System Design of Power Tracking for PEM Fuel Cell Automotive Application

“…The proton exchange membrane fuel cell (PEMFC) is one of the most promising energy conversion alternatives to the internal combustion engine, because of its high energy conversion efficiency, high power density, low operating temperature, zero emissions, and quick start‐up . However, there are still challenging issues to be solved for widespread commercial application of PEMFC systems in vehicles, one of which is fast and efficient power tracking under severe and frequent load changes .…”
