Resumen o descripción
This paper presents a mathematical model applied to a continuous hydrogen production
system, composed of a stirred fermenter connected to a biocatalyzed electrolysis cell (BEC).
The model contemplates two differential equation systems which describe the adaptation
(start-up) and continuous phases between the fermenter and the BEC. The proposed model
describes the dynamics of hydrogen and volatile fatty acid (VFA) production and substrate
consumption (glucose for the stirred fermenter and acetate in the BEC), based on a Tessiertype
bacterial kinetic which simulates the lag phase in the bacteria. A hybrid evolutionary
algorithm and least squares method were used to estimate the parameters. Model validation
and simulation were achieved by obtaining the volumes of hydrogen and VFAs
produced and the statistical bacterial density via the most probable number (MPN) method.
