Study of Current Distribution in PEMFC Stack Using Magnetic Sensor Probe

Experimental Study of Non-Destructive Approach on PEMFC Stack Using Tri-Axis Magnetic Sensor Probe

“…In order to evaluate the fault such as flooding, measured the z component of the magnetic field and variations in voltage have been used [14].…”

“…This method has advantages of being non-destructive and enabling non-contact measurement. In the past, the Nexa Power module 1.2-kW PEMFC stack under the steady state has been evaluated [14] [15]. In this study, current distribution was investigated to determine the operating state of a 300-W-class PEMFC stack using a new tri-axial magnetic sensor probe.…”

Evaluation of Current Distribution in a PEMFC using a Magnetic Sensor Probe

“…In the previous study [5,6], the Z component of magnetic flux density B z ʹ was used to evaluate faults such as flooding because B z correlates to the current parallel to the cell surface. This ratio is defined as follows:…”

“…The advantage of this method is that it does not affect the PEMFC, because the Available online at www.sciencedirect.com measurement is non-destructive and makes no electrical contact. In the past, the Nexa Power module under the steady state, and a 20-cell stack under flooding conditions, have been evaluated [4,5,6]. In this study, the current distribution was investigated and evaluated under steady and dry-out conditions in PEMFC cells.…”

Experimental investigation of stable the proton exchange membrane fuel cell control using magnetic sensor probes

“…Previously, for installation in an actual PEMFC system, we had developed a measurement method using a magnetic sensor inserted in the cooling hole of the PEMFC stack. The Nexa power module was evaluated under steady‐state [34] with a 20‐cell stack under flooding [35] and dry‐out conditions [36]. The proposed method was shown to be effective by comparing the measured and simulated magnetic distributions [37].…”
