Quick crossover current measurement of a polymer electrolyte fuel cell stack with and without cell voltage terminals
Hiroyuki Gunji, Mika Eguchi, Fumiaki Sekine, Yasuyuki Tsutsumi
Journal of Power Sources   409 6-12   2019   [Refereed]
Crossover current (COC) measurement is an important diagnostic
methods for a polymer electrolyte fuel cell. Although a COC measurement
method for single cells has already been established, a considerable
amount of time is required to individually ...

We have investigated the influence of the concentrations of both the chloroplatinic acid and sodium borohydride solution on the formation of the Pt nanoparticles in this study.A lower chloroplatinic acid concentration and higher sodium borohydride...
Gas-leak-induced pinhole formation at polymer electrolyte membrane fuel cell electrode edges
Hiroyuki Gunji, Mika Eguchi, Fumiaki Sekine, Yasuyuki Tsutsumi
International Journal of Hydrogen Energy   42(1) 562-574   Jan 2017   [Refereed]
Pinhole formation in the membrane is a polymer electrolyte membrane fuel cell (PEMFC) failure mode typically due to mechanical causes. This study reports the discovery of thermal pinhole formation caused by a gas leak.
The study was prompted...
Durable Marimo-like carbon support for Platinum nanoparticle catalyst in polymer electrolyte fuel cell
Electrochimica Acta   213 447-451   Jul 2016   [Refereed]
This study deals with the electrochemical stability of carbon-based catalyst supports as the cathode material of a polymer electrolyte fuel cell (PEFC). The platinum catalyst on the carbon black supports (Pt/CB) was investigated for use in the PE...
