Agglomeration of Platinum Particles Supported on Carbon in Phosphoric Acid
TL;DR: In this paper, the growth of a platinum particle supported on an acetylene black was investigated fundamentally using a potential perturbation method in phosphoric acid at 205°C and atmospheric pressure.
Journal ArticleDOI
Thick vacuum deposited silicon films suitable for the anode of Li-ion battery
TL;DR: Vacuum deposited silicon film on a Ni foil substrate showed very stable Li charge/discharge performance in PC containing 1M LiClO 4, however, became poorer rapidly with the increase in the film thickness as discussed by the authors.
Patent
Methanol fuel cell
TL;DR: In this article, the methanol permeability coefficient of the solid film is at most 1 x 10-6 mol/mol/l (min.min.cm2).

TL;DR: In this article, a methanol concentration control device is disposed, at a pipe which supplies the fuel to the fuel cell for controlling the amount of the methanoline in the pipe by detecting the open-circuit voltage of the unit cell or the opencircuit potential of the oxidant cell at the control device.
Journal ArticleDOI
Phosphoric Acid Absorption and Performance of Gas Diffusion Electrode
TL;DR: In this paper, the relationship between acid absorption of the catalyst layer and performance of the gas diffusion electrode in a phosphoric acid fuel cell was investigated, together with the size of pores available for the cathode and anode reactions.
