Data for phase angle shift with frequency
Data in Brief, 2016 Phase angle shift between the current and voltage with frequency has been reported for a single phosphoric acid fuel cell in the cell temperature from 100 °C to 160 °C and the humidifier temperature from 40 °C to 90 °C.

Future lines of research on phase angle: Strengths and limitations
Reviews in Endocrine & Metabolic Disorders, 2023 Bioelectrical impedance analysis (BIA) is the most widely used technique in body composition analysis. When we focus the use of phase sensitive BIA on its raw parameters Resistance (R), Reactance (Xc) and Phase Angle (PhA), we eliminate the bias of using
