dc.description.abstract | In this paper we analyze the energy and power achievable by means of a re-
cently proposed salinity gradient technique for energy production. The method,
denominated soft electrode or SE, is based on the potential di erence that can
be generated between two porous electrodes coated with cationic and anionic
polyelectrolytes. It is related to the Capacitive Donnan Potential (CDP) tech-
nique, where the electrical potential variations are mostly related to the Donnan
potential, of ion-selective membranes in the case of CDP, and of the polyelec-
trolyte coating in SE. It is found that although SE is comparable to CDP in
terms of energy production, it presents slower rates of voltage change, and lower
achieved power. The separate analysis of the response of positively and neg-
atively coated electrodes shows that the latter produces most of the voltage
rise and also of the response delay. These results, together with electrokinetic
techniques, give an idea on how the two types of polyelectrolytes adsorb on the
carbon surface and a ect di erently the di usion layer. It is possible to suggest
that the SE technique is a promising one, and it may overcome the drawbacks
associated to the use of membranes in CDP. | es_ES |
