Nº publicación JP2016513215A 12/05/2016
PURPOSE: An algorithm of a numerical model for metal hydride
Resumen
alloy tank interpretation is provided to produce a temperature, a
reaction rate, and a change of hydrogen concentration of MH alloy
according to hydrogen reaction only with numerical model calculation
for various types of MH alloy tanks, thereby removing various aspects
of constraints such as device manufacturing costs, experiment costs,
or time. CONSTITUTION: An initial hydrogen concentration within
MH alloy, an initial temperature and an initial reaction velocity value
are inputted. A residual hydrogen concentration within the MH alloy
depending on reaction flow is calculated, and a reaction temperature
according to heat of reaction depending on the reaction flow is
calculated. The reaction flow is calculated at a fixed time interval
defined by formula 2. The residual hydrogen concentration calculation
step, the reaction temperature calculation step, and the reaction flow
calculation step are repeated according to an interpretation period and
the time interval.

APPARATUS AND PROCESS FOR CARBON MONOXIDE SHIFT CONVERSION, AND HYDROGEN PRODUCTION
EQUIPMENT
Nº publicación JP2016074603A 12/05/2016
A shift conversion catalyst layer is divided into at least two front and
Resumen
back stages. A first catalyst and a second catalyst are provided on the
upstream side and the downstream side, respectively. The first catalyst
has a property that a carbon monoxide conversion rate decreases with
an increase in carbon dioxide concentration in a supplied reaction gas
at a constant carbon monoxide concentration in the supplied reaction
gas and a constant reaction temperature. The first catalyst is combined
with the second catalyst such that the degree of decrease in carbon
monoxide conversion rate with respect to an increase in carbon
dioxide concentration in the supplied reaction gas in the second
catalyst is lower than that in the first catalyst.; Whereby, the
conversion rate of a carbon monoxide concentration of a carbon
monoxide shift conversion apparatus can be improved without
increasing the used amount of a shift conversion catalyst.

direction on an opposite side of the cell stack (102S) from the cover
portion (503), that includes one end portion in the stacking direction
connected to the end plate (190) and another end portion in the
stacking direction connected to the case (500), and that fastens the cell
stack (102S), the end plate (190), and the case (500) to each other. A
thermal expansion coefficient of the cover portion (503) is larger than
a thermal expansion coefficient of the fastening member (300).
